The U.S. government unsealed papers Monday detailing the arrest and interrogation of a senior terror leader, a development one official called “an intelligence watershed.”For the past two years, Ahmed Warsame has been cooperating with U.S. interrogators, revealing inside details about training, operatives and potential plots.
Warsame was a key commander for al Shabaab, the al Qaeda-linked terrorist group based in Somalia. Al Shabaab has attracted dozens of American recruits, including Omar Hammami, a propagandist born in Alabama.
