The director of the U.S. Central Intelligence Agency says the United States has not underestimated the threat posed by the Islamic State group.
John Brennan said Monday the success by the United States and its coalition countries in containing the group's momentum inside Iraq and Syria is "why I think they are looking abroad" to make attacks.
Asked whether the U.S. had underestimated the threat, Brennan said, "I don't think we are underestimating the capability of ISIL," using an alternate name for the group.
He told an audience at the Center for Strategic and International Studies, a Washington think tank, that while it was "inevitable" that the Islamic State will try to carry out such attacks, "to me it is not inevitable that they are going to succeed."

Activists say French airstrikes on the northern Syrian city of Raqqa did not kill civilians and only hit military targets in the Islamic State group's de facto capital.
Rami Abdurrahman, who heads the Britain-based Syrian Observatory for Human Rights, said Monday the French targeted military facilities on the northern and southern edges of the city.
He says there are casualties among IS but did not provide numbers.
Sarmad al-Jilane, of the Raqqa-based collective called Raqqa is Being Slaughtered Silently, said the city is tense, with few people venturing out even though markets are open.
France's Defense Ministry said 12 aircraft dropped a total of 20 bombs Sunday night in the biggest air strikes since France extended its bombing campaign against the extremist group to Syria in September.

A French police union is calling for the Molenbeek neighborhood of Brussels, which authorities consider a focal point for extremists and fighters, to come under EU security control, saying the government has ceded the area to the Islamic State group.
The neighborhood, which police raided Monday in a sweep for the fugitive Frenchman suspected in the Paris attacks, was home to the Belgian Islamic State jihadi believed to be behind the attacks and two other thwarted attempts.
The France Police union said Belgium's national institutions failed and demanded "necessary measures to protect the Belgian and European populations from terrorism." The EU has no provisions for the demand, which appeared to be largely a sign of frustration with what some are calling a massive security failure.

A senior Turkish official says authorities flagged one of the suicide bombers in the Paris attacks to their French counterparts back in 2014 but received no response.
The official said Monday that Turkish authorities identified Omar Ismail Mostefai as a possible "terror suspect" in October 2014. It notified French authorities in December 2014 and in June 2015.
The official said Turkey had no response from France until after the Paris attacks when it requested information on Mostefai.
The Paris prosecutor's office says Mostefai had been flagged as having ties to Islamic extremism five years ago.
The Turkish official said Mostefai entered Turkey in 2013 but authorities have no record of him leaving. He said Mostefai's case shows that intelligence-sharing and effective communication are crucial to counter-terrorism efforts.
The official cannot be named because of rules barring civil servants from speaking to reporters without authorization.

The Paris prosecutor's office says two more suicide bombers involved in deadly attacks in the French capital have been identified.
Prosecutors said Monday that one suicide bomber who blew himself up in the Bataclan music hall Friday night was Samy Amimour, a 28-year-old Frenchman charged in a terrorism investigation in 2012. He had been placed under judicial supervision but dropped off the radar and was the subject of an international arrest warrant.
Prosecutors say three people in Amimour's family entourage have been in custody since early Monday.
A suicide bomber who blew himself up outside the national soccer stadium was found with a Syrian passport with the name Ahmad Al Mohammad, a 25-year-old born in Idlib. The prosecutor's office says fingerprints from the attacker match those of someone who passed through Greece in October.
