China's official media including Xinhua reported that on April 30, 2014 morning an explosion, suspected to be the handiwork of Uyghurs, occurred at the railway station in Urumqi, capital of the restive Xinjiang-Uyghur Autonomous Region. 

This is probably the first time that Uyghurs protesting against the Chinese government have been accused of using high explosives. 

Chinese President Xi Jinping had visited Urumqi just days earlier.

The explosion follows the attack earlier this month at the railway station in Kunming, capital of the minority-peopled Yunnan Province, where dozens of people were reported to have been killed and hundreds injured by knife-wielding Uyghurs. This spread panic among people in China and prompted authorities to deploy armed police personnel at sensitive places, including hotels, in all cities across China.
