Bombs were planted outside Dallas Police headquarters in an attack early on Saturday that may have involved as many as four gunmen firing automatic weapons, police said.

Dallas Police Chief David Brown told reporters that a motive for the attack was not yet known, but he also said there had been threats and attacks on police elsewhere in the country in the past few months.

One of the devices, a pipe bomb, exploded when a police robot attempted to move it. Another, which was under a police vehicle, was detonated by a bomb squad, according to the police department.
