A series of explosions in the western Chinese province of Xinjiang has killed at least two people and injured many, according to the local government.

A brief notice about the multiple blasts in Xinjiang's Luntai county appeared on local government website Tianshan eight hours after the explosions happened.

It said the fatal blasts injured many people, and that local police responded quickly.

The Tianshan report did not say what caused the explosions, or give a precise number of injured.

Violent and often deadly attacks continue to be mounted in the western Chinese province despite intense security and an official war on terrorism.

The Chinese government fears religious extremists have infiltrated its borders from neighbouring Pakistan and Afghanistan.

It also blames an overseas separatist movement for instigating the violence in Xinjiang.

Clashes between locals and security forces in Xinjiang - home to the mostly-Muslim Uighur minority - as well as attacks targeting civilians, have killed more than 200 people in the past year.

The controversial trial of an ethnic Uighur scholar will see a verdict tomorrow.

Economist Ilham Tohti faces separatism charges and will more than likely be sent to gaol. Human rights groups say it is a way of silencing a government critic.
