BEIJING (REUTERS) - A Sinopec oil pipeline has been damaged in an accident in southwest China, spilling 2,000 tonnes of gasoline near a railway construction site and halting a train service, state news agency Xinhua reported on Wednesday.

The accident, in which at least three people were injured, came just days after a deadly explosion at a major crude oil pipeline operated by the state refiner in eastern China that killed 55 and forced a halt at port operations.

The incident in the southwestern province of Guizhou occurred at midnight Tuesday when a construction tower collapsed at a high-speed rail construction site in Anshun city, Xinhua reported, citing rescue workers.

Workers were repairing the broken pipeline and clearing the site, which is about 30 meters from the rail tracks, with residential houses nearby, the report said.

Local authorities have evacuated residents within a 2 km (1.3 mile) radius of the site and ordered a train service from Anshun to the provincial capital of Guiyang to be suspended.

Sinopec officials were not available to comment.
