Hundreds of extra police officers are on the streets of Manchester following Thursday's deadly synagogue attack.

Assistant Chief Constable Chris Sykes said Greater Manchester Police (GMP) officers had been working 12-hour shifts and had rest days cancelled since the attack, while other forces had also contributed officers.

The Conservative Party Conference in Manchester, due to start on Sunday, had also been factored into police planning and operations, said ACC Sykes, who stressed that his force had the resources needed to reassure the city's Jewish population and other communities.

"We've got lots of officers and staff out there - very, very visible," he said.

"We have got extra patrols," he explained. "So we have our normal policing [and put] an awful lot of extra staff into certain communities and here into the city centre."
