     MUMBAI-Indian commandos battled into the early hours of Friday to end a multiple hostage crisis

in Mumbai after suspected Islamic militants killed 125 people across the city.

      Officials said they had almost totally cleared the luxury Taj Mahal hotel where gunmen had been held

up for more than 24 hours.

      Indian security forces personnel released hostages from Nariman House in Mumbai. Thirty-nine

people were rescued from the five-star Oberoi hotel,where " mopping up(清理火场) "  operations were

still underway,police said.

     Indian Prime Minister Manmohan Singh said the militants had come from "outside the country".

       The Press Trust of India said one Pakistani militant had been arrested,although Pakistan's

government fiercely denied any involvement.

     Indian media reports said between six and nine foreign nationals were among the dead in

Mumbai-including a Japanese businessman,an Australian,a Briton,a German and an Italian.

      At least five gunmen had been shot dead and one captured,police said. Fourteen security personnel

were also killed,including the head of Mumbai's anti-terror squad.

     To draw maximum intemational attention,the militants used small groups to attack a total of about a

dozen targets in India's financial hub,including the main railway station,a hospital and a restaurant popular

with tourists.

      An unknown group calling itself the Deccan Mujahedeen claimed responsibility,with one gunman

telling an Indian TV channel by phone that the outfit(装备) was of Indian origin and motivated by the

treatment of Indian Muslims.

     Up to 327 people were reported wounded.

      The main Bombay Stock Exchange was closed until further notice,as were shops,schools and

businesses.

         Prime Minister Singh said the aim had clearly been to spread panic by choosing high profile(知

名度度的)  targets and "indiscriminately(随心所欲地) killing foreigners".

      Witnesses said the gunmen had been very particular in their choice of hotel hostages.  "They said

they wanted anyone with British and American passports," said one British guest at the Taj Mahal hotel.
