Three people responsible for a fire that killed 11 people and severely injured two others in northeast China's Jilin province in 2011 were executed Thursday, court officials said Thursday.

Wang Jiansong, Qu Long and Wang Lu were convicted of setting fire to a bar. The fire spread to the upper floors of a budget hotel on May 1, 2011, said officials with the Intermediate People's Court in the city of Tonghua.

The three were found to have set fire to a basement bar, in a bid to seek revenge on the bar's owner, with whom they had had disputes, officials said.

Their death sentences were approved by the Jilin provincial Higher People's Court.

Eleven people, including hotel tenants and firefighters who responded to the accident, were killed as the fire spread to a karaoke bar and later to the guestrooms of budget hotel chain Home Inns. The fire also caused about 1.8 million yuan (285,478 U.S. dollars) in economic losses.
