Update: Bomb-making material, rifles, ammunition and a combat journal have been found at the home of the suspect in the Dallas shooting

BBC reports that Bomb-making material, rifles, ammunition and a combat journal have been found at the home of the suspect in the Dallas shooting, officials say.
Five police officers were killed and seven wounded in a hail of gunfire during a protest on Thursday against the shooting of black men by police.

The suspect, 25-year-old Micah Johnson, died after a long stand-off with police in central Dallas.
Mayor Mike Rawlings said officials believed he was "the lone shooter".
"We believe now the city is safe," the city mayor said at a news conference on Friday.
The protest in Dallas took place after this week's deaths of Philando Castile in Minnesota and Alton Sterling in Louisiana.

Officials said on Friday that gunmen targeted police officers and civilians in separate attacks in Georgia, Missouri and Tennessee in the aftermath of the Minnesota and Louisiana deaths.
In Tennessee, a black army veteran killed a woman and also injured three other people, including a police officer, as he opened fire on a motorway on Thursday morning.
