RUSSIA'S security service said today that it has detained a suspect in the killing of a senior general in Moscow.

The suspect was described as an Uzbek citizen recruited by Ukrainian intelligence services.

Lieutenant General Igor Kirillov was killed on Tuesday by a bomb hidden in a scooter outside his block of flats in Moscow, a day after Ukraine’s security service levelled criminal charges against him. His assistant also died in the attack. A Ukrainian official said the service carried out the attack.
