Mumbai (ABC) -- Indian police and witnesses say gunmen have targeted luxury hotels, a popular tourist attraction and a crowded train station in at least seven coordinated shooting attacks in India's financial capital Mumbai, wounding at least 25 people.
State police commissioner AN Roy said several people had been wounded in the attacks and police were battling the gunmen.
Roy said early on Thursday "the terrorists" used automatic weapons and grenades in some places.
He added that the encounters were "still going on" and that police were trying to"overpower them."
Gunmen opened fire on two of the city's best known luxury hotels, the Taj Mahal and the Oberoi.
They also attacked the crowded Chhatrapati Shivaji Terminus station in southern Mumbai and Leopold's restaurant, a Mumbai landmark.
It was not immediately clear what the motive was for the attacks.
At the Oberoi, police officer P.I. Patil said shots had been fired inside and the hotel had been cordoned off.
He would not give any other details.
The Press Trust of India news agency quoted Mumbai General Railway Police Commissioner AK Sharma as saying that several men armed with rifles and grenades were holed up in the train station.
Leopold's restaurant was riddled with bullet holes and there were blood stains on the floor and shoes left by fleeing customers, according to an Associated Press reporter at the scene.
At least 25 people had been brought to the GT Hospital near the shootings, hospital officials said.
