More Will Be Assassinated In The Coming Days! Do You Like The Work Of Our Assassins? Get Your Own Sniper" was the message of a Black Power Political Organisation on its Facebook account.
A Facebook page claiming to represent a black power group has posted messages claiming responsibility for the deaths of five police officers, seven injured, and two injured civillians in Dallas.
Five officers were gunned down by at a sniper or more, who picked out officers from an 'elevated position' - believed to be a multi-storey car park.
The account has since been taken down but not known yet weather it was removed by Facebook or the group itself.
The group has posted dozens of statements on alleged racially-motivated incidents and threatening violent action over at least the several months.
