Eleven gas stations found to have safety flaws in Shanghai were ordered to suspend operations following a fatal gas station blast on Saturday that killed four people, according to the Shanghai municipal government.

Twenty others undergoing renovations were also ordered to stop construction in preparation for inspection, according to the city government's publicity office.

An explosion occurred at a Shanghai gas station on Saturday when workers were carrying out maintenance work on an oil tank, killing two workers and two passers-by. The city's work safety authority is also planning to relocate certain gas stations that are near schools and kindergartens, the office said.
