Washington: A man armed with a rifle threw incendiary devices at an immigration jail in Washington state early Saturday morning, then was found dead after four police officers arrived and opened fire, authorities said. The Tacoma Police Department said the officers responded at about 4 am to the privately run Tacoma Northwest Detention Center, a US Department of Homeland Security detention facility that holds migrants pending deportation proceedings.

The detention center has also held immigration-seeking parents separated from their children under President Donald Trump's "zero tolerance" policy, an effort meant to deter illegal immigration. The shooting took place about six hours after a peaceful rally in front of the detention center, police spokesman Loretta Cool said. She said another rally was planned for later Saturday, but it would have to be held in a different area because of the investigation into the police shooting. Police said the man caused a vehicle to catch fire and that he attempted to ignite a large propane tank and set buildings on fire. Police said that besides the rifle, he had a satchel and flares. Police said officers called out to the man, and shots were fired.
