Obama calls for calm after three police officers killed in Baton Rouge shootings:
July 18, Washington: US President Barack Obama has called for restraint after three police officers were shot dead in the city of Baton Rouge in Louisiana.
The gunman, an African-American who had served for five years in the Marines, was also killed, reports said.
Tensions in the city have been high since a black man Alton Sterling was shot dead by police two weeks ago.
It remains unclear whether Sunday's incident was related to that death and a second police killing in Minnesota.
Those two deaths spared protests across the United States and triggered a revenge attack by a black army veteran who shot dead five officers in the city of Dallas.
In a live broadcast from the White House, President Obama called upon all Americans to unite and refrain from divisive language.
A vigil was attended by police officers and members of the public on Sunday evening at Saint John the Baptist Church in Zachary, just north of Baton Rouge.
