UPDATE: Thursday, April 26, 2012

Increased intelligence chatter has U.S. counterterrorism officials concerned about violence from al-Qaida's affiliate in Yemen.

An intelligence official tells The Associated Press that in the past six months, counterterrorism officials have seen what they consider an increase in intelligence about potential threats from the Yemen group, known as al-Qaida in the Arabian Peninsula. That's the group believed to be behind the failed attempt to bring down a jetliner over Detroit on Christmas in 2009.

A joint intelligence bulletin from U.S. Northern Command, the FBI and Homeland Security Department says officials are worried that the terror group "intends to advance plots along multiple fronts, including renewed efforts to target Western aviation." The AP has obtained a copy of the bulletin.

The terror group is considered the most active al-Qaida affiliate.

The bulletin also raises concerns that terrorists could be planning attacks on or about the anniversary of Osama bin Laden's death. Officials say there is no indication of any credible or specific threat, but they're urging law enforcement to be on the watch.

It was last May 2 when U.S. special forces killed Bin Laden in a raid on his compound in Pakistan.

Counterterrorism officials say there is no credible or specific threat to the U.S. related to the upcoming anniversary of the death of terror leader Osama bin Laden.

A joint intelligence bulletin from U.S. Northern Command, the FBI and Homeland Security Department urges Americans to be vigilant because al-Qaida and like-minded groups continue to want to attack the U.S., and some have pledged to avenge bin Laden's death.

But officials say there is currently no intelligence pointing to a specific threat.

Bin Laden was killed last year in a May 2 raid by the U.S. military. He was living in a compound in one of Pakistan's suburbs.
