Manchester attack: Up to 3,800 troops will be deployed on streets

Up to 3,800 soldiers will be deployed on the streets in the wake of the Manchester terror attack, Home Secretary Amber Rudd has said.

The heightened security response after Britain's worst terror attack since the 7/7 bombings in 2005 comes as investigators race to determine whether attacker Salman Abedi acted alone or was part of a wider group.

Ms Rudd earlier told Sky News the 22-year-old suicide bomber, who was born in Manchester and was of Libyan descent, was known "up to a point" to the intelligence services.
