Police have arrested the Greenpeace climate protesters who closed part of a key oil export waterway for 18 hours by tying themselves to a bridge and dangling over the water. The closure of one portion of the Houston Ship Channel, which stretches 53 miles (85 km) from its entrance in the Gulf of Mexico to the Port of Houston, blocked tanker ship traffic to and from five major oil refineries as well as chemical and oil-export terminals. Twelve people were taken into police custody shortly after 5 p.m., Thursday, according to spokesmen for Greenpeace and the Harris County Sheriff’s office.
