UK: Black Lives Matter blocks London's Heathrow Airport

Black Lives Matter UK campaigners blocked roads leading to London's largest airport as part of a series of nationwide protests Friday. Some transport routes in other British cities came to a standstill, with demonstrators chaining themselves together in Birmingham and Nottingham. More protests were planned in Manchester. The UK-wide protests mark five years since 29-year-old black man Mark Duggan was shot and killed by police in north London. His death sparked riots across the capital and other British cities. "In the UK, families have in some cases been waiting decades to find out what's happened to their loved ones who have died in custody, or to get a straight answer -- even where wrongdoing has been found to be by police officers," Black Lives Matter UK spokesman Wail Qasim, 23, told CNN. "So this demonstration comes after a decade-long struggle and it's to highlight what's happening." Starting around 8:20 a.m. (3:20 a.m. ET), several demonstrators began chaining themselves together and lying across the M4 motorway leading to Heathrow Airport beneath a banner reading: "This is a crisis." Ten people were arrested, said London's Metropolitan Police.<br/>
