Four officers killed, seven wounded in Dallas shooting protest

Four police officers were fatally shot and seven wounded in one of the worst shootings of police in the US.

Four police officers were fatally shot and seven wounded in one of the worst shootings of police in recent U.S. history, by snipers who targeted them during rallies in Dallas to protest against the fatal shooting of two black men by police this week.

Dallas Police Chief David Brown told a news conference that two snipers in elevated positions shot 11 officers, killing three, in what appeared to be a coordinated attack. A fourth officer died, police said later on Twitter. At least one more was in surgery. Some of the victims were shot in the back.
