US Accidentally Killed Two Al Qaeda Hostages

President Barack Obama has said he "profoundly regrets" the accidental deaths of two hostages in a US counter-terrorism operation in January on the Pakistan-Afghan border. Mr Obama told a White House news conference the US had believed the target was an al Qaeda compound with no civilians present. He said the operation also killed al Qaeda members. Two other Americans - both al Qaeda leaders - were killed in US raids in the same region, according to a White House statement.
