http://www.bbc.co.uk/news/uk-england-manchester-40076241Tens of thousands of runners are taking to the streets on an emotional day for Manchester days after the arena attack that killed 22 people.
Armed police have been stationed among spectators at the Great Manchester Run, the latest large-scale event to take place since Monday's suicide bombing.
A huge round of applause for the emergency services followed a minute's silence for the victims and casualties.
Runners set off under the banner #RunForManchester.

"I heart Manchester" signs were dotted around the city, while runners and spectators are wearing yellow ribbons and bee symbols in a show of solidarity.
Oasis hit Don't Look Back in Anger was played on the loudspeakers following the minute's silence, a song which was spontaneously performed by a crowd after a silence in St Ann's Square in central Manchester on Thursday.
'Incredibly emotional'
Greater Manchester Police (GMP) gave the go-ahead for Sunday's athletics event, with additional security measures in force.
It includes Europe's largest 10km run and, for the first time, a half-marathon.
