Mumbai: Indian police on Tuesday released the names of nine suspected militants killed during their attack on Mumbai, bolstering India's charges that all of them came from Pakistan.

At a briefing on Tuesday, chief police investigator Rakesh Maria gave the names and the aliases used by the gunmen in the attacks. He also showed photographs of eight of the men - some taken from identity cards, while others were gruesome shots of the dead attackers.

No photograph was released for one of the men because his body was too badly burned, Maria said.

Maria also gave details of the districts and towns in Pakistan from where the gunmen are believed to have come. He did not say how police had tracked down their hometowns, although they have been interrogating the lone surviving gunman.

India has blamed the Pakistani-based militant group Lashkar-e-Taiba for the attacks that left 171 people dead in India's financial center last, and have demanded that Pakistan take action.

Pakistan has intensified its crackdown on a militant group suspected in the Mumbai terror attacks by arresting 20 more people but said Tuesday it will not hand any of its citizens over to India.

The United States is pressing Pakistan to help catch those behind the attack, and avert a crisis between the nuclear-armed neighbors that would harm efforts against the Taliban and Al Qaida.

Also on Tuesday, the new head of a Jewish centre in Mumbai vowed to restore the facility that was devastated when the gunmen rampaged through the city ten days earlier. The owners of the iconic Taj Mahal hotel, meanwhile, pledged to reopen with an interfaith ceremony.
