VANCOUVER, Wash. (AP) - More than 100 protesters formed a human blockade on tracks in Vancouver as a response to a recent fiery oil train derailment along the Columbia River.

Organizers with the Fossil Fuel Resistance Network, a group that formed after the June 3 Mosier train derailment, said before they protest they expected to be arrested. Twenty-one protesters ended up being taken into custody.

Protesters gathered at 9th and Daniels streets at 9 a.m. and walked to the BNSF Railway and Amtrak Station on West 11th Street, according to police. They began sitting on the tracks at 10 a.m. The arrests were made at around 12:30 p.m.

According to a news release, Saturday's protest is being held to highlight risks associated with fossil fuel extraction, transportation and consumption. Some participants are holding signs that read "Ban the bomb train."

Nobody was injured in the derailment and less than 10 gallons of oil entered the river. The derailment forced evacuations in Mosier, about 70 miles east of Portland. Since then, state transportation officials in Oregon have asked for a halt of the massive oil trains because of concerns over the strain they put on the rail tracks.
