Met Police to boost armed officers in wake of Paris attacks

Hundreds of extra armed officers are to be trained to help counter the threat of a terrorist attack in London, the Metropolitan Police is set to announce.

It comes after Scotland Yard reassessed its ability to stop terrorism and respond to armed attacks in the light of last year's deadly attacks in Paris.

Some 600 extra officers are expected to receive firearms training, in addition to 2,000 already trained in London.
