Four police officers were killed in downtown Dallas as crowds protested the fatal shootings of two African-American men by police in Louisiana and Minnesota.
Dallas police said a total of 11 officers were shot during the protests, including the four shot dead.
The police are negotiating with a suspect at a parking garage in downtown Dallas, Chief David Brown said. Police have been exchanging gunfire with the suspect for 45 minutes.
“The suspect has told our negotiators that the end is coming,” Brown said.

The suspect said more officers are going to be hurt, and added that there are bombs placed in downtown Dallas.
