President Trump tweeted Sunday night, “Changes to our thought process on terror must be made,” following the latest attack linked to the Islamic State in France after less than two months of calm.

“At some point countries will have to open their eyes & see what is really going on. This kind of sickness & hatred is not compatible with a loving, peaceful, & successful country!” Trump wrote.

A 20-year-old Frenchman born in Chechnya rampaged through a festive Paris neighborhood Saturday evening slashing passers-by with a knife, investigators said. The man, identified as Khamzat Azimov, killed one person and wounded four others in a festive area near Paris’ old opera house. Police shot him to death as he charged them, witnesses said.

ISIS quickly claimed responsibility for the Saturday night attack via its Amaq news agency, saying Azimov was a “soldier” of the terror group.

In a video before the attacks, as Fox News reported, Azimov apparently called on ISIS supporters living in the West to immigrate to the group’s so-called “caliphate,” or else carry out attacks locally.

“They have closed the doors of immigration in our faces, so let’s strike them in the center of their homes,” the man said in French, adding, “We are on the truth ... despite the alliance of all these unbelievers against us, they will not fulfill their goal.”

Trump often has made the case that Europe ought to respond more to terrorism like the U.S. does.

In early May to the National Rifle Association, Trump claimed that gun-toting Parisians could have thwarted Islamic State attackers at Paris’ Bataclan concert hall.

Trump sparked controversy as some in France took offense at his "trigger-firing" hand gesture imitating the Bataclan attackers. Multiple extremists with explosive belts and assault weapons killed 130 people in the 2015 attacks on the Bataclan, Paris cafes and the national stadium.

Laying out his case for dropping the Iran nuclear deal, Trump contended, "If we do nothing, we know exactly what will happen. In just a short period of time, the world’s leading state sponsor of terror will be on the cusp of acquiring the world’s most dangerous weapons."

Along those lines, Trump is set to host NATO Secretary-General Jens Stoltenberg at the White House Thursday to discuss NATO’s role in the international fight against terrorism.

Last month, French President Emmanuel Macron professed a sunny, best-friends relationship, telling Trump that together the U.S. and France would defeat terrorism, curtail weapons of mass destruction in North Korea and Iran, and act together on behalf of the planet.

Secretary of State Mike Pompeo said the United States would lend a hand in the Paris investigation.

“The French authorities with all the intelligence help the United States can provide will do our best to unpack this in the coming hours,” Pompeo said on “Fox News Sunday.”

In a statement released Sunday evening, White House press secretary Sarah Sanders added: “Acts like this only strengthen the resolve of the global coalition to defeat ISIS and drive it out of existence.”

The ISIS "soldier" who stabbed people on a Paris street was on an anti-terror watchlist of suspected extremists, Sky News reported Sunday.

Three friends of the Chechnyan-born attacker have been taken in for questioning since Saturday night’s attack near the Paris Opera which killed one man and wounded four others.

Police killed the 20-year-old man, identified by the president of Chechnya, Ramzan Kadyrov, as Khasan Azimov, according to the Associated Press.

Law enforcement said the suspect’s name was on the "S file" watchlist of people suspected of radicalized views who could pose a threat to national security, according to the Sky News report.

SUSPECT IN DEADLY PARIS KNIFE ATTACK WAS NATIVE OF CHECHNYA, OFFICIAL SAYS

Azimov was a French citizen and had no record of arrests or criminal activity.

Cops picked up Azmimov’s parents in the northern 18th district of Paris after the stabbing.

They third person being questioned was an Azimov friend was detained Sunday in the eastern French city of Strasbourg.

The Islamic State terror group claimed responsibility for the attack.

A French judicial official not authorized to speak publicly said the suspect was born in November 1997, which made him 20 now. Initial reports said he was 21.

Paris prosecutor Francois Molins told reporters that witnesses heard the suspect shouting, "Allahu Akbar" -- "God is great" in Arabic.

A police source said he also shouted, “Kill me or I kill you,” Sky News reported.

Police union representative Rocco Contento said officers shot the suspect as he ran at them shouting, “I will kill you. I will kill you.”

Six suicide bombers from one family — including children and teens — rode in on motorcycles and attacked three churches in Indonesia during Sunday Mass, killing at least 13 people and wounding dozens more, police and media reports said.

The family accused of carrying out one of the worst attacks against Indonesia's Christian minority had been in Syria, where ISIS had controlled a large territory in the area until recently, Indonesia’s national police chief Tito Karnavian said. The father, two sons ages 18 and 16, and the mother with two children ages 12 and 9 all took part in the deadly church bombings.

All three attacks targeting Sunday Mass congregations occurred in Surabaya, a city of around 2.8 million people in a country that holds the world’s largest Muslim majority, Reuters reported. At least 13 people, including the family members, were killed and more than 40 people were injured in the blasts. 

The first attack that killed four people, including one or more bombers, occurred at the Santa Maria Roman Catholic Church, police told reporters at the scene. Two police officers were among more than 40 wounded, they said. The father of the family accused of carrying out the suicide bombing had detonated a car bomb during his attack.

The incident was followed by a second explosion at the Christian Church of Diponegoro that killed two people. In a third attack, at Pantekosta Church, two more died, police said.

A witness described the woman with two children, saying she was carrying two bags at the Diponegoro church.

"At first officers blocked them in front of the churchyard, but the woman ignored them and forced her way inside. Suddenly (the bomb) exploded," said a civilian guard named Antonius.

Shattered glass and chunks of concrete littered the entrance of the Santa Maria Church, which was sealed off by heavily armed police. Rescue personnel treated victims on a nearby field while officers inspected wrecked motorcycles in the parking lot that were burned in the explosion.

A street merchant outside the church said she was blown back several yards by the powerful blast. She said she saw two men riding on a motorbike, which Karnivan said the two teenage boys had used in their attack.

"I saw two men riding a motorbike forced their way into the churchyard. One was wearing black pants and one with a backpack," said Samsia, who uses a single name. "Soon after that the explosion happened."

There was no immediate claim of responsibility for the deadly attacks.

26 PEOPLE KILLED IN BURUNDI 'TERRORIST' ATTACK: OFFICIAL

The latest attacks came days after police ended a riot and hostage-taking at a detention center near Jakarta that left six officers and three inmates dead. The Islamic State terrorist group has claimed responsibility.

Indonesia has carried out a sustained crackdown on militants since bombings by Al Qaeda-affiliated radicals in Bali in 2002 killed 202 people.

Churches have been previously targeted in central Jakarta at Christmas in 2000 that killed about 20 people, Reuters reported.

Indonesia has seen a “recent resurgence in homegrown militancy,” the wire service reported.

The Nigerian Army rescued more than 1,000 people held captive by the Boko Haram terror group, officials announced Monday.

The country's military broke the news on Twitter, saying troops from the 22 Brigade conducted an operation in conjunction with allies of the Multinational Joint Task Force to free the hostages.

Troops targeted the villages of Malamkari, Amchaka, Walasa and Gora villages in the northeastern Borno State where the group has based its nearly decade-long insurgency.

"The hostages consisted mainly of women, children, as well as some young men who were forced to become Boko Haram fighters," the army said. "Speaking with one of the rescued victims, Alhaji Gambo Gulumba from Amchaka village, thanked the Nigerian military for showing them love and care."

The army added that the action is part of its resolve to "rout out BH" and rescue all hostages.

"The public is also advised to report any suspicious character to the appropriate authority for prompt action. However, the rescued persons are being attended to in a military medical facility," the army said.

BOKO HARAM ATTACKS NIGERIA'S MAIDUGURI, KILLING AT LEAST 2

The army's action comes just over a week and a half after two people were killed and seven others were wounded in an attack by Boko Haram extremists in Nigeria's northeastern city of Maiduguri.

The extremists attacked the Jidari Polo area near the Federal High Court before they were repelled by security forces in a gun battle.
