British Prime Minister Theresa May confirmed during the pre-dawn hours on Sunday that the deadly incidents that took place at approximately 10:00 p.m. on Saturday just after midnight are "being treated as a potential act of terrorism." May said, “This is a fast-moving investigation.: She added, "I want to express my huge gratitude to the police and emergency services who are on the scene. Our thoughts are with those who are caught up in these dreadful events.”
Police responded to reports of a vehicle colliding with pedestrians on the London Bridge at about 10 p.m. local time. The BBC reports that more than more one person died during the incident on London Bridge in which a vehicle drove at a high rate of speed, mowing pedestrians down. There are reports that some victims fell into the River Thames. First responders are looking for injured or dead victims.
There are reports that as many as seven persons are dead, and at least 20 injured. Metropolitan Police tweeted a warning to the public, telling people in the areas affected to run to safety, hide, and then call police if it is safe to do so. People are leaving central London with their hands held up as police and military secure the area. Police reported that they responded to a reports of stabbings in Borough Market, and after officers responded "shots have been fired." At least two potential terrorists were shot and possibly killed.
London Bridge is usually crowded on Saturday nights, and Borough Market is a popular with tourists and Londoners because of its bars and restaurants near the bridge.
A witness who identified himself as Tony Murphy told SkyNews that he heard a significant amount of gunfire at least 10 minutes near the bridge before police arrived.
A BBC reporter who was on London Bridge at the time of that incident reported that several people were injured when a white van swerved and struck a crowd of people crossing the bridge over the Thames. "A white van driver came speeding -- probably about 50 mph -- veered off the road into the crowds of people who were walking along the pavement," Holly Jones told BBC News. "He swerved right round me and then hit about five or six people. He hit about two people in front of me and then three behind. I'd say there are about four severely injured people. They all have paramedics assisting them at the moment."
The attack resembled one that occurred on Westminster Bridge and the Houses of Parliament in March, as well as a deadly attack in France on July 14, 2016. Jones reported that four people were severely injured on the bridge and that some 20 armed police officers were on the scene.
The State Department released a statement condemning the attack. "The United States stands ready to provide any assistance authorities in the United Kingdom may request. 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." The American Embassy in London declared, "We are closely monitoring the incidents in London. Our thoughts are with the family and friends of those affected by this terrible situation." It added, "We stand ready to provide all possible consular assistance should we become aware of any affected U.S. citizens."
