UPDATE: Seven Dead in London Violence

Police in Britain say as many seven people are dead following at least two incidents in central London.

Multiple news agencies report that a white van drove into a crowd of pedestrians Saturday night at London Bridge in the heart of the British capital. London Metropolitan Police reported seven people were killed in the attack.

Police also say that three suspects believed to be involved in the attack at that location were killed by officers.

The bridge itself is expected to remain closed overnight and the nearby London Bridge underground station was also closed. However, boats on the Thames River were allowed to pass under the bridge again after several hours.

Shortly after, an attack took place at historic Borough Market, not far from London Bridge. Police and the BBC say that two people entered a restaurant at the market and stabbed two people, one of them a server. The identity or condition of the victims have not been disclosed.

Shortly after these attacks, a separate incident occurred in the Vauxhall area of southwest London. It was later determined that this involved was a stabbing and it was not connected to the London Bridge or Borough Market situations.

The London Ambulance Service tweeted that at least 40 people from both affected areas have been taken to local hospitals. Other victims were treated for injuries on the spot and released.

British prime minister Theresa May is being briefed on the incidents. May has described the incidents as “potential acts of terrorism”.

Canadian Prime Minister Justin Trudeau says that government officials have been monitoring what has happened in Britain, which Trudeau calls “awful news” in a tweet.  US President Donald Trump has been briefed on the situation and has telephoned May to offer condolences. The US State Department meanwhile has condemned the attacks as “cowardly”.
