This country, which had sought to show solidarity with Islamist groups and allow religious figures a greater role in public life, has recently reversed course, moving forcefully to curb the influence of Muslim conservatives in its mosques, public universities and charities.

The government has asked imams for recordings of their Friday sermons and started to strictly monitor religious schools. Members of an influential Muslim women's group have now been told to scale back activities like preaching or teaching Islamic law. And this summer, more than 1,000 teachers who wear the niqab, or the face veil, were transferred to administrative duties.

The crackdown, which began in 2008 but has gathered steam this summer, is an effort by President Bashar Assad to reassert Syria's traditional secularism in the face of rising threats from radical groups in the region, Syrian officials say.

The policy amounts to a sharp reversal for Syria, which for years tolerated the rise of the conservatives. And it sets the government on the seemingly contradictory path of moving against political Islamists at home, while supporting movements like Hamas and Hezbollah abroad.

Syrian officials are adamant that the shifts stem from alarming domestic trends and do not affect support for those groups, allies in their struggle against Israel. At the same time, they have spoken proudly about their secularising campaign. Some Syrian analysts view that as an overture to the United States and European nations, which have been courting Syria as part of a strategy to isolate Iran and curb the influence of Hamas and Hezbollah.

Human rights advocates say the policy exacerbates pressing concerns: the arbitrary imprisonment of Islamists, as well as the continued failure to integrate them in political life.

Pressure on Islamic conservatives in Syria began in earnest after a powerful car bomb exploded in the Syrian capital in September 2008, killing 17 people. The government blamed the radical group Fatah al-Islam.

“The bombing was the trigger, but the pressure had been building,'' said Peter Harling, a senior analyst with the International Crisis Group. “After a period of accommodation with the Islamic groups, the regime entered this far more proactive and repressive mode. It realises the challenge that the Islamisation of Syrian society poses.''

The government's campaign drew wider notice this summer, when a decision to ban students wearing the niqab from registering for university classes was compared to a similar ban in France. That move seemed to underscore a reduced tolerance for strict observance by Muslims in public life. Syrian officials have put it differently, saying the niqab was “alien'' to Syrian society.

The campaign carries risks for a secular government that has fought repeated, violent battles with Islamists in the past, mostly notably in the 1980s, when tens of thousands of people were killed. For the moment there has been no visible domestic backlash, but one cleric, who said he was dismissed without being given a reason two years ago, suggested that could change.

“The Islamists now have a strong argument that the regime is antagonising the Muslims,'' he said.

Syrian analysts say the government has complex motives. They point out that it courted religious conservatives when Syria was isolated internationally amid accusations that it was behind the assassination of a former Lebanese Prime Minister, Rafik Hariri. The government appointed a sheikh instead of a member of the ruling Ba'athist party to head the Ministry of Religious Affairs, and allowed, for the first time, religious activities to take place in the stadium at Damascus University.

As the country emerged from that isolation, it focused on domestic threats from sectarianism in neighbouring countries and the growing influence of the Islamists.

“What they had nourished and empowered, they felt the need to break,'' said Hassan Abbas, a Syrian researcher who studies cultural trends.

The details of the campaign have remained murky, though Syrian officials have not been afraid to publicise its aims, including in foreign media outlets. In an interview with U.S. talk show host Charlie Rose in May, Mr. Assad was asked to name his biggest challenge.

“How we can keep our society as secular as it is today,'' he said. “The challenge is the extremism in this region.'' — New York Times News Service
