Cairo - CIA warns of more attacks but Obama rules out ground troops to fight Daesh; France declares war on terrorism
The Daesh terror group warned in a new video on Monday that countries taking part in air strikes against Syria would suffer the same fate as France, and threatened to attack in Washington.
Lending credence to the threat, CIA director John Brennan warned that the attacks in Paris were likely not a "one off event" and that he expects the Daesh group has more operations in the pipeline.
However, US President Barack Obama ruled out a shift in strategy in the fight against Daesh, saying putting US troops on the ground to combat the group "would be a mistake".
"There will be an intensification of the strategy that we put forward but the strategy that we put forward is the strategy that ultimately is going to work," Obama told reporters. "But ...it is going to take time."
French President Francois Hollande called on the US and Russia to join forces to destroy Daesh. "France is at war. But we're not engaged in a war of civilisations, because these assassins do not represent any. We are in a war against terrorism which is threatening the whole world," he said in a sombre speech to both houses of parliament.
French Interior Minister Bernard Cazeneuve said police had arrested nearly two dozen people and seized arms, including a rocket launcher and automatic weapons, in 168 raids overnight. Another 104 people were put under house arrest, he said.
The Daesh video, which appeared on a site used by the group to post its messages, begins with news footage of the aftermath of Friday's Paris shootings in which at least 129 people were killed.
The message to countries involved in what it called the "crusader campaign" was delivered by a man dressed in fatigues and a turban, and identified in subtitles as Al Ghareeb the Algerian.
"We say to the states that take part in the crusader campaign that, by God, you will have a day, God willing, like France's and by God, as we struck France in the centre of its abode in Paris, then we swear that we will strike America at its centre in Washington," the man said.
'Al Ghareeb the Algerian' also warned Europe in the video that more attacks were coming. "I say to the European countries that we are coming, coming with booby traps and explosives, coming with explosive belts and (gun) silencers and you will be unable to stop us because today we are much stronger than before," he said.
The CIA chief said the Paris attacks by gunmen in suicide vests were carefully planned and executed. "Security and intelligence services right now are working feverishly to see what else they can do in terms of uncovering it," he said.
"This was not something done in a matter of days. This is something that was carefully and deliberately planned over the course of several months in terms of whether they had the operatives, the weapons, explosives, suicide belts. I would anticipate that this is not the only operation Daesh has in the pipeline," he said. - Agencies
