DUBAI: The ideological leader of Yemen-based Al-Qaeda in the Arabian Peninsula was killed in a drone strike this week, allegedly by the United States, AQAP said in a statement published Tuesday.

Ibrahim Al-Rubaish, who in January accused France of surpassing the United States as the top enemy of Islam, was killed with several other militants in a “crusader raid” on Monday, the statement said.

The statement published online was apparently referring to a drone attack that killed six suspected militants in their vehicle in Hadramawt province in southeast Yemen.

The United States, whose intelligence agencies consider AQAP to be the most dangerous branch of the terror network, is the only country that operates drones over Yemen.

Rubaish from the Qassim region “has spent two decades of his life in jihad, fighting America and its agents,” the AQAP statement said.

He fought in Afghanistan and was held in the US military prison in Guantanamo for “a few years” before he joined AQAP following his release, it said.

AQAP has seized Mukalla, the capital of Hadramawt province.

US Defense Secretary Ashton Carter acknowledged last week that Al-Qaeda was making gains and that the fighting in Yemen was complicating counter-terrorism efforts, but vowed that they would continue.
