U.S. officials believe extremists across northern Africa, emboldened by the terror attack on a natural gas plant in Algeria, are growing more daring.
A senior American intelligence official tells CNN that "what we have seen is intelligence suggesting a desire to carry out more attacks" against western and U.S. interests in the region.
The United States is not aware of any specific threats, the official said.
But one of those believed to be plotting is Moktar Belmoktar, a veteran militant who has claimed responsibility for the attack this month on the BP facility in eastern Algeria that left at least 37 hostages dead.

The United States has signed a deal with the central African nation of Niger to host American troops and surveillance drones to keep tabs on Islamic militants in the region, officials from those countries said Tuesday.
Niger is next door to Mali, where France joined the fight against Islamic rebels earlier this month
Pentagon spokesman George Little said the role of U.S. troops in Niger "has not yet been defined" - but Niger's ambassador to the United States, Maman Sidikou, told CNN that his government has agreed to let U.S. drones operate from its territory.
Sidikou says his understanding of the agreement is the drones will be unarmed and used for surveillance to monitor extremist movements. He refused to discuss where in the country the drones would be based or when they will be operational.
Niger lies to the east of Mali, where French troops and warplanes are fighting alongside government troops to push back Islamist fighters who seized much of the former French colony in 2012.
The rebels took advantage of the chaos that followed a revolt by Touareg separatists and a military coup, and banned music, smoking, drinking and watching televised sports in the territories under their control. FULL POST
