Revenge Attack: 5 Policemen Killed, 7 Injured in Dallas, USA

In what appeared to be a revenge attack, a black United States of America (USA) Army reservist, Mr. Micah Xavier Johnson who served in the Afghan war yesterday shot dead no fewer than five police officers, injuring seven others.

The suspect reportedly said he wanted to "kill white people" in revenge amidst protest decrying police shootings of black men, officials said.

Seven other police officers and two civilians were wounded in the ambush in downtown Dallas, Texas, USA on Thursday night, officials said. Police killed the gunman, identified by a U.S. government source as Micah Xavier Johnson, using a bombcarrying robot after an hour-long standoff.

The shooting sent swarms of protesters running in panic in the streets as police officers came under fire.

The shootings, the latest major gun violence to rock USA took place toward the end of a march protesting incidents earlier in the week in Louisiana and Minnesota in which police fatally shot black men in confrontations whose bloody aftermath was caught on video.

The Dallas shootings came during a week of heightened emotions over police use of force against black suspects and raised fears that others might seek to retaliate against police.

"This was a well-planned, well-thought-out, evil tragedy by these suspects. And we won't rest until we bring everyone involved to justice," Dallas Police Chief David Brown said. "We are determined to not let this person steal this democracy from us."

During lengthy negotiations with police, the gunman said "the end is coming," Brown told reporters.

"He said he was upset about the recent police shootings," said Brown, who is black. "The suspect said he was upset at white people. The suspect stated that he wanted to kill white people, especially white officers."
