SAN FRANCISCO, April 14 (Xinhua) -- A group of demonstrators in Portland in the U.S. northwest state of Oregon rallied late Saturday in protest against U.S.-led air strikes on Syria, a local TV report said.

The protest was organized by Peace and Justice Works of Portland, an Oregon non-profit organization advocating peace, justice, the environment and human rights in the state.

The non-profit body said on its official website early Saturday that it was organizing an "emergency action" to protest the U.S.-led bombing of Syria that also involved Britain and France on Friday.

"The U.S. has no United Nations authorization, much less (U.S.) Congressional authority, to wage war on the government of Syria," it said in an announcement.

"With the presence of the Russian military, engaging in such reckless violence is extremely dangerous," it added.

On Friday, U.S. President Donald Trump ordered the U.S. forces to launch missile strikes on targets in Syria for its alleged use of chemical weapons against civilians in the country.

Russia has reacted strongly to the air strikes and warned of "consequences."

"Again, we are being threatened. We warned that such actions will not be left without consequences," the Russian embassy in the United States tweeted on Friday.
