An explosion at a Bombay McDonald's hurt at least 17 people Friday, police said.

According to Reuters, the city's fire department got a call from the fast-food outlet that a gas cylinder had exploded. The restaurant was in a railway station.

Police, after a preliminary investigation, determined that a problem with the air-conditioning system was more likely to have caused the blast.

"It certainly does not look like an explosive. It looks like some fault in the air-conditioning duct," Ahmad Javed, Bombay's joint commissioner of police, told Reuters.

On Thursday, a blast at a McDonald's restaurant on the Indonesian island of Sulawesi killed three people celebrating the end of the Muslim holy month of Ramadan.

Initially also blamed on a gas cylinder, that explosion was later deemed by police to have been caused by a bomb.

Less than a week ago, two people were killed by a bomb on a Bombay bus.

Friday was the 10th anniversary of the destruction of a mosque by Hindu militants that caused massive Hindu-Muslim riots across the country, as well as the second day of the three-day Islamic holiday of Eid al-Fitr, which marks the end of Ramadan.

McDonald's restaurants have been frequent targets of anti-American sentiment worldwide, even though almost all branches are owned by local franchisees.
