Men Suspected of Killing British Soldier Were Known to Security Services

Both being treated at hospitals after being shot by police

(Reuters) - Britain's security services faced questions on Friday over whether they could have done more to prevent the murder of a soldier hacked to death in a busy London street after it emerged that his suspected killers were known to intelligence officers.

The two suspects, Michael Adebolajo, 28 and Michael Adebowale, 22, are under guard in hospitals after being shot and arrested by police after the murder of 25-year-old Afghan war veteran Lee Rigby on Wednesday in broad daylight. They have not yet been charged.
