Two people are missing after falling into the sea when strong wind brought by a typhoon hit an oil drilling platform in China, officials said Wednesday.

The valve on the oil rig has been closed and there is no risk of an oil spill, the platform's operator, Shengli Oilfield, a subsidiary of Sinopec, said in a statement.

The Shengli Oilfield No. 3 drilling platform leaned over 45 degrees when typhoon Malou struck Bohai Bay Tuesday evening, Xinhua reported. Four people fell into the sea while 32 were trapped on the platform.

Rescuers were still searching for the two who fell into the sea, while 34 people were saved early Wednesday.
