Flames that engulfed a port in Dalian, a coastal city in northeast China's Liaoning Province, were basically extinguished Saturday morning, 15 hours after blasts hit two oil pipelines.

The fire and explosion caused no casualties, a city government spokesman said at a briefing at 10 a.m. The fire site was far from residential areas. As of Saturday morning, fire fighters had switched off valves on all oil tanks and put the flames under control, said Xu Guochen, secretary-general of the city government.

He said more than 2,000 men and 338 fire engines from 14 cities across the province worked through the night to extinguish the fire.

The accident aroused the attention of China's top leadership, prompting instructions from President Hu Jintao and Premier Wen Jiabao. Vice Premier Zhang Dejiang rushed to the fire site Friday night to direct the rescue work.

China's Air Force sent two Y8 aircraft to the rescue operation, carrying 17.8 tonnes of fire extinguishing agent. The fire site was still overshadowed by smog Saturday morning.
