From Daily Mirror (UK):
Update: A 2nd attack may have happened nearby
Up to 20 people are feared to be injured after a van reportedly ploughed into pedestrians on London Bridge in a suspect terrorist attack.
The vehicle mounted the pavement at the scene in central London this evening, according to shocked witnesses.
It comes just two months after a terrorist mowed down pedestrians at Westminster Bridge before stabbing an unarmed cop. Five victims were killed in the attack.
There are unconfirmed witness reports from the scene at London Bridge tonight that people may have been stabbed and as many four people were severely hurt.
Metropolitan Police have confirmed there is also another incident at nearby Borough Market and armed police are at both scenes.
A witness told Reuters she saw people with apparent knife wounds on the bridge.
