Over 200 people are still trapped inside Hotel Trident in Mumbai and five to six staff members of the luxury hotel have been killed in the night-long terror attack.

"Altogether there would be around 200 people inside the Oberoi complex in Mumbai. We believe that not less than 100 people are at the Oberoi side and not less than 100 people inside the Trident side," Vice Chairman of Oberoi Hotels S S Mukherjee told a TV channel.

The plush hotel is currently surrounded by army and NSG commandos in order to launch an offensive to flush out the holed up terrorists and rescue hostages.

India should get its act together 

"We have definite information that the casualty of our staff is about five-six people," he said.

Putting last night's occupancy at the hotel to be around 375-385, Mukherjee said the terrorists "have not gone down the basement and have only gone to the upper floors".

He assured that other staff members are safe and secure and that they are "very concerned about guests, dignitaries, employees and other staff who are trapped inside".

"We have very little information about what is happening inside...what we can hear is that people are generally inside the room," he said.
