Mumbai, India’s financial capital again became a terrifying battleground, complete with gun battles, explosions and a raging fire last night.

At least 101 people, including six foreign tourists were killed in the city last night after gunmen turned it into a war zone, shooting people in luxury hotels and setting off explosions in one of the worst terrorist attacks in the country's history. In response, police killed four gunmen and also arrested nine suspected terrorists from the city.

Anti-Terrorism Squad chief Hemant Karkare, who was probing the Malegaon blast case, and another senior IPS officer were among those who were killed in separate encounters with terrorists at various places across the city.

Apart from targeting city's main business hotels, the Taj Mahal, Trident and Oberoi, the terrorists also targeted the main railway station, Chhatrapati Shivaji Terminus; the domestic airport; Leopold's, a popular tourist café; a hospital; and other locations.

The police said that an unspecified number of terrorists used AK-47s, rifles and hand grenades. Speaking from Mumbai’s control room, a senior police officer, Ramesh Tayde said, “At least six foreigners have been killed and the death figure has gone up to 101 now.”

Meanwhile, criticizing the terrorists attack Maharashtra Chief Minister Vilasrao Deshmukh said, “This is a most audacious attack. It is a very serious situation and gun battles are still on in at least three places.”

Prime Minister Manmohan Singh also condemned the terror attacks in Mumbai and assured all help to Maharashtra in meeting the situation. The Prime Minister’s Office said Singh was in touch with Maharashtra Chief Minister Vilasrao Deshmukh and was monitoring the situation.
