Attack In Paris

PARIS — President François Hollande of France called on Monday for constitutional amendments to fight potential terrorists at home and for an aggressive effort to “eradicate” the Islamic State abroad.
His call to arms — “France is at war,” he said at the opening of his remarks to a joint session of Parliament — came as security forces in France and Belgium zeroed in on a suspect they said was the architect of the assault that killed 129 people Friday night in Paris. The suspect, a 27-year-old Belgian, has fought for the Islamic State in Syria and has been linked to other terrorist attacks.
Mr. Hollande spoke after the French police raided homes and other sites across the country in an effort to head off possible further attacks and as the authorities in Belgium hunted for a suspected assailant in Friday’s attacks. Mr. Hollande called for quick action by Parliament on new legislation that would give the government more flexibility to conduct police raids without a warrant and place people under house arrest. He said he would seek court advice on broader surveillance powers. And he called for amendments that would enable the state to take exceptional security measures without having to resort to the most drastic options currently in the Constitution.
Mr. Hollande is also seeking to extend the current state of emergency for three months and let the government strip the citizenship of French natives who are convicted of terrorism and hold a second passport.
“Our democracy has prevailed over much more formidable opponents than these cowardly assassins,” Mr. Hollande said a day after France conducted airstrikes against the Syrian city of Raqqa, the self-proclaimed capital of the Islamic State. It was the country’s most intense military strike yet against the radical group, which has claimed responsibility for the attacks in Paris.
The French leader said he would meet soon with President Obama and President Vladimir V. Putin of Russia in an effort to settle on a united campaign to wipe out the Islamic State, also known as ISIS or ISIL.
“Terrorism will not destroy the republic, because it is the republic that will destroy it,” he said. 

Three days after the attacks on a soccer stadium, a concert hall and numerous bars and cafes, French and Belgian security services were focused on the radical jihadist they believe was the leader of the plot, Abdelhamid Abaaoud. He is among the most prominent Islamic State fighters to have come out of Belgium.
A French official briefed on the investigation, who spoke on the condition of anonymity because he was not authorized to discuss operational details, said Mr. Abaaoud had mentioned plans to attack “a concert hall” to a French citizen who returned from Syria.
Mr. Abaaoud, this official said, had also been in contact with Ismaël Omar Mostefaï, one of the Paris attackers. Mr. Abaaoud also knew another attacker, Ibrahim Abdeslam; they were tried together in 2010 in Belgium for a minor offense.
Mr. Hollande said the attacks had been “planned in Syria, organized in Belgium, perpetrated on our soil with French complicity.”

The French authorities said Monday that they had conducted 168 raids across the country in an effort to root out possible terrorist threats. The raids extended from the Paris region to the major cities of Lille, Lyon, Marseille and Toulouse, they said. They also said they had arrested 23 people and detained 104 others under house arrest.
But a Frenchman believed to be involved in the Paris attacks, Salah Abdeslam, 26, a brother of Ibrahim Abdeslam, remained at large, eluding a series of raids conducted by the authorities in Molenbeek, the working-class Brussels neighborhood where the brothers lived.
A third brother, Mohamed, and four other men who had been detained in Belgium were released on Monday. At a news conference in Brussels, Mohamed said he did not know Salah’s whereabouts and added, “My parents are under shock and have not yet grasped what has happened.”as the Abdeslam brothers.
Mr. Abaaoud was already a suspect, according to officials and local news reports, in a failed terrorist plot in Belgium in January and an attempt in August to gun down passengers on a high-speed train to Paris from Brussels. An intelligence official said the authorities feared he might be in Europe.
In Washington, Representative Adam B. Schiff of California, the senior Democrat on the House Intelligence Committee, said some American officials suspected that Mr. Abaaoud might still be in Syria. Mr. Abaaoud was most likely part of an Islamic State cell that has developed over the past year to help plan, organize and execute terrorist attacks in Europe, particularly in France, Mr. Schiff said in a telephone interview. 
The cell is believed to be led by Abu Mohammed al-Adnani, who serves as an official spokesman for the Islamic State, a Defense Department official said Monday.
Mr. Schiff warned that much was still unknown about how much of the plot had been directed from Syria and how much autonomy had been left to conspirators.cities — Delhi; Doha, Qatar; and Dublin — crowds gathered at French embassies to pay their respects.
As France observed its second of three days of national mourning, the authorities in France and Belgium raced to track down suspects and chase leads.
At one house in the Rhône department in the southeast, around Lyon, the police found a Kalashnikov rifle, three pistols, ammunition and bulletproof vests. Officers then obtained a warrant to search the home of the parents of a man who lived in the house, where they found several automatic pistols, ammunition, police armbands, military clothing and a rocket launcher.
Prime Minister Manuel Valls and Interior Minister Bernard Cazeneuve promised to keep up the search. “We are using all the possibilities given to us by the state of emergency, that is to say administrative raids, 24 hours a day,” Mr. Valls said. He vowed to keep intense pressure on “radical Islamism, Salafist groups, all those who preach hatred of the Republic.”
