Seven people are feared dead after three men with 12-inch hunting knives reportedly stabbed revellers after mowing down up to 20 people with a white van on London Bridge.
The men, described as being 'of Mediterranean origin', reportedly jumped out of the van and began 'randomly stabbing people' along Borough High Street in central London at 10pm.
One woman said she saw three people with what appeared to be their throats cut on London Bridge amid reports that at least seven people have been stabbed, leaving bodies 'strewn' on the road in central London.
The car is believed to have veered in an 'S shape' at 50mph across the bridge and has driven towards the Shard and is south of the river.
'Rapid gunfire' was heard in the London Bridge area as armed police are thought to have shot dead two of the men, with a search underway for the third man.
One person has been killed at London Bridge - and one of the casualties is reportedly a police officer.
Armed police have also responded to reports of stabbings in nearby Borough Market and shots have been fired
