RAMALLAH, West Bank — Muslims from the Middle East to Britain and Austria condemned Sunday the Mumbai shooting rampage by suspected Islamic militants as senseless terrorism, but also found themselves on the defensive once again about bloodshed linked to their religion.

Intellectuals and community leaders called for greater efforts to combat religious fanaticism.

Indian police said Sunday that the only surviving gunman told them he belongs to the Pakistani militant group Lashkar-e-Taiba. The group is seen as a creation of Pakistani intelligence to help fight India in the disputed Kashmir region. Another group, Jaish-e-Mohammed, has also operated in Kashmir. Both are reported to be linked to al-Qaida.

Ten gunmen attacked 10 targets in the three-day assault including a Jewish community center and luxury hotels in India's commercial hub. More than 170 people were killed.

Many Muslims said they are worried such carnage is besmirching their religion.

"The occupation of the synagogue and killing people in hotels tarnishes the Muslim faith," said Kazim al-Muqdadi, a political science lecturer at Baghdad University. "Anyone who slaughters people and screams 'Allahu Akbar' (God is Great) is sick and ignorant."

In Britain, home to nearly two million Muslims, a spokesman for the Muslim Council of Britain, Inayat Bunglawala, said that "a handful of terrorists like this bring the entire faith into disrepute."

A previously unknown Muslim group, Deccan Mujahideen, claimed responsibility for the attacks. The name suggests origins in India.

Pakistan has denied involvement and demanding that India provide proof. In Pakistan, Jamaat-ud Dawa, an Islamist group believed to have ties to Lashkar-e-Taiba, denounced the killing of civilians.

In Islamic extremist Web forums, some praised the Mumbai attacks, including the targeting of Jews.

A man identified as Sheik Youssef al-Ayeri said the killings are in line with Islam.

"It's all right for Muslims to set the infidels' castles on fire, drown them with water .... and take some of them as prisoners, whether young or old, women or men, because it is one of many ways to beat them," he wrote in the al-Fallujah forum.

In the Gaza Strip, the territory's Islamic militant Hamas rulers declined comment. Hamas has carried out scores of suicide attacks in Israel, killing hundreds of civilians in recent years. However, Hamas has said it does not want to get involved in conflicts elsewhere.

Iranian President Mahmoud Ahmadinejad referred to the attacks as terrorism, but added that the violence is rooted in "unjust policies" aimed at destabilizing the region. He did not elaborate.
