Net widens in search for accomplices in London Bridge attack

May did not answer repeated questions from reporters on Monday on the police cuts she oversaw but said counter-terrorism budgets had been protected and police had the powers they needed.

Butt had appeared in a documentary called "The Jihadis Next Door", broadcast a year ago by Britain's Channel 4, as part of a group of men who unfurled an Islamic State flag in a park.

Butt was previously known to police and the domestic spy agency, MI5.

"However, there was no intelligence to suggest that this attack was being planned and the investigation had been prioritized accordingly", he said.

The three attackers were shot dead by police after driving into pedestrians on London Bridge and stabbing people in Borough Market. Seven people died and 48 were injured. And just two days before the United Kingdom election, Prime Minister Theresa May has faced a barrage of criticism for cutting 20,000 officers from the police force in her time as Home Secretary.

Assistant Commissioner Mark Rowley said an investigation into Butt had been downgraded as there was no evidence he posed an imminent threat. "We have constant attacks going on, not just there but across the globe, and we have to start putting national security and global security at an all time high", she told a White House briefing.

Mr. Khan said: "Not unreasonably, these questions are being asked".

"This vigil shows the people that did this that they can not divide us", he said.

After the incident on the bridge, the three men abandoned the vehicle, ran down a set of stairs and began attacking people with knives in the nearby Borough Market area on the south side of the Thames, police said.

Meanwhile, further searches were carried out in Ilford in east London overnight as the police inquiry continues.

The 42-year-old mother of three was working at a local school when she noticed Butt, who was also known as Abu Mohamed, meeting with local children and trying to draw them into his radicalism.

Redouane, 30, who claimed to be Moroccan-Libyan, also lived in Barking, east London. He also used the name Rachid Elkhdar.

Transport for London, which oversees the capital's transport network, has advised commuters to make alternative journeys as the station will be busy.

The killer was caught on camera alongside two notorious hate preachers and attempted to unfurl an ISIS flag in Regent's Park.

President Donald Trump is criticizing London's mayor on Twitter after he sought to reassure residents about a stepped-up police presence on city streets following a deadly attack there.

"I phoned the anti-terrorist hotline, I spoke to the gentleman, told him why and how, I told him about our conversation and how and why I think he'd been radicalised, and basically you know just doing my bit". There's an election on now, there's a choice for everybody. Editor Geoff Ho was photographed walking toward an ambulance on the arm of a police officer with a makeshift bandage on his neck.

In a series of tweets late Saturday and early Sunday, Trump challenged London Mayor Sadiq Khan for saying there was "no reason to be alarmed".

The Labour Party has promised to increase the number of police officers and to strengthen neighborhood security programs to fight terror. Prime Minister Theresa May has come under fire for her role reducing ranks of cops.
