An explosion hit a chemical plant today in eastern China, the official Xinhua state news agency said, citing local authorities.

No casualties have been reported yet, Xinhua said.

The blast, which triggered a fire, happened around 8.50pm local time in Huantai county in Shandong province.

The explosion occurred at a factory of Shandong's Runxing Chemical company, according to the official People's Daily.

More than 10 fire engines were at the scene trying to put out the fire, the People's Daily reported, citing an eyewitness.

Windows shattered in the village where the blast occurred, state media said, and tremors reverberated within 2 kilometres (1 mile) of the site of the explosion.

The explosion comes after two huge blasts ripped through a warehouse storing dangerous chemicals in Tianjin on Aug. 12 killing at least 121 people.
