Police said that, of the ten militants who arrived in Mumbai for the attacks, nine have been killed and one has been captured.

Commandos and rescue personnel continue to clean up the wreckage near the still-smouldering Taj Mahal Palace Hotel after the final battle inside.
Pakistani President Asif Ali Zardari, battling Islamic radicals in his own nation, said he would cooperate.
'If any evidence comes of any individual or group in any part of my country, I shall take the swiftest of action in the light of evidence and in front of the world,' he told CNN-IBN TV.
Many guests, trapped in their rooms in the Taj Mahal while the battle raged around them, emerged to harrowing scenes after the killing of the militants.
The gunmen had set parts of the 105-year-old hotel ablaze as they evaded scores of India's best-trained commandos. They left bodies in their wake, some with grenades stuffed into their mouths or concealed underneath.
The surviving gunman has told interrogators they wanted to go down in history for an Indian version of the 11 September attacks on the US, according to local television reports.
Authorities said 22 foreigners were among the dead, including three Germans, three Israelis, one US citizen, one Australian, a British, two Canadians, an Italian, a Japanese, a Singaporean, a Mauritian, a Thai and a Chinese national.
Five were unidentified, they said.
