A gasoline bomb set off by a former bank cashier in the north-western province of Gansu in China killed dozens of people on Friday.

The Xinhua News Agency reported that the blast went off at the Rural Credit Cooperatives in Tianzhu Tibetan Autonomous County in the city of Wuwei at around 8:30 a.m., when all the bank employees were having a meeting.

The Tianzhu Government informed that the cashier, Yang Xianwen harbored a grudge against the bank after he was fired last month from his job due to embezzlement charges. On Friday, he threw a bottle filled with gasoline inside the meeting room setting it ablaze.

Threatened by the situation, a number of people reportedly tried to escape by jumping from the meeting room window onto a neighboring three-story building.
