DALLAS - Hillary Clinton and Donald Trump have put off political events out of respect for five police officers fatally shot during a protest in Dallas.

Clinton, the presumptive Democratic nominee, has postponed a rally scheduled for Friday in Pennsylvania, but still plans to travel to Philadelphia for a scheduled appearance at the African Methodist Episcopal Convention.

Trump has canceled his plans to address Hispanics in Miami on Friday.

The presumptive Republican nominee denounced the police deaths as "a coordinated, premeditated assault on the men and women who keep us safe." Clinton says she is mourning the officers killed "while doing their sacred duty to protect peaceful protesters."

Seven other police officers and two civilians were injured in the shooting attack during the rally to protest killings of black men by white police officers.
