The US military and intelligence are “deeply involved” in top secret operations in Yemen in collaboration with Yemeni troops, according to media reports. “Yemeni troops in the past six weeks have killed scores of people, among them six of 15 top leaders of a regional Al Qaeda affiliate, sources told the newspaper. The operations were approved by President Barack Obama and begun six weeks ago and involve several dozen troops from the U.S. military's clandestine Joint Special Operations Command. A Yemeni official told the Associated Press Tuesday that the U.S. military and intelligence agencies have been participating in joint operations for some time with Yemeni troops, and the two countries are currently in discussions to build a new aviation unit to help bolster Yemen's counterterrorism forces. The official, who spoke on condition of anonymity to discuss military operations, said that while the intelligence sharing has been critical, the Yemen military badly needs helicopters for its counterterrorism operations. U.S. officials have said repeatedly that American advisers do not take part in raids in Yemen, but provide intelligence, surveillance, planning and other weapons assistance.”
