Attackers drove a van at high speed into a group of pedestrians on the London Bridge Saturday before stabbing others near Borough Market in what police are calling terrorist incidents.
The London ambulance service said it had transported at least 48 people to different hospitals, and police confirmed that at least seven were dead following the attacks.
London police told reporters they believed they had killed all of the attackers involved.
{mosads}Officials said Sunday that 12 people had been arrested in east London in connection with the investigation.
Prime Minister Theresa May released a statement saying the incident was being investigated as a “potential act of terrorism”, but the government has not officially called the incidents terrorist attacks.
According to London Police, two areas were locked down.
A BBC reporter said a van appeared to be traveling at 50 miles per hour when it drove up on the pavement, hitting several pedestrians on the London Bridge.
According to multiple reports, a suspect then began stabbing people at random near Borough Market.
President Trump was briefed on the incidents around 6:30 p.m. ET and later tweeted a response in which he renewed his call for courts to approve his executive order banning travel into the U.S. from six Muslim-majority countries.
“We need to be smart, vigilant and tough. We need the courts to give us back our rights,” Trump tweeted Saturday evening. “We need the Travel Ban as an extra level of safety!”
“Whatever the United States can do to help out in London and the U. K., we will be there – WE ARE WITH YOU. GOD BLESS!” Trump wrote in a second tweet.
The White House said in a statement that the president had also spoken with May on the phone, offering his support to the country.
The U.S. State Department also released a statement Saturday night condemning the act.
“The United States condemns the cowardly attacks targeting innocent civilians in London this evening. We understand UK police are currently treating these as terrorist incidents,” the statement read. “Our hearts are with the families and loved ones of the victims. We wish a full and quick recovery to those injured in the attacks.”
