British police have arrested 13 men suspected of planning terrorist attacks.
Police said Tuesday they raided several homes in and around London and in the counties of Hertfordshire, Bedfordshire, and Lancashire. They say the search of those homes will take some time.
A police statement says the men were arrested on suspicion of committing, preparing, or instigating acts of terrorism.
All 13 suspects are said to be in their 20s and 30s, but no other information about them was immediately available.
