Eight people locked themselves to construction equipment and a work trailer Monday to delay construction of the Keystone XL pipeline in Oklahoma.
The action occurred on a TransCanada Corporation work site east of Seminole, Okla., about 60 miles southeast of Oklahoma City and 130 miles north-northwest of Hugo, Okla.
According to NewsOK.com, four people who chained themselves to an excavator decided to abandon the protest for their own safety by about 9 a.m.
One protestor, Fitzgerald Scott, who was arrested in April at another protest, reportedly was injured when firefighters tried to use a hydraulic tool to remove protesters from the equipment, NewsOK.com said.
The action was organized by the group Great Plains Tar Sands Resistance, which said that a total of eight people locked themselves to TransCanada equipment. In addition to the four locked to an excavator, four were locked to an office trailer, according to the organization's Facebook page. The group said that 10 activists were arrested. NewsOK.com reported that at least nine arrests were made.
