SINGAPORE (Reuters) - Singapore has banned two Muslim foreign preachers from entering the city-state because their views bred intolerance and were a risk to its social harmony, the government said on Monday.

The decision to block Ismail Menk, identified by local media as a Zimbabwean and Haslin bin Baharim as a Malaysian, is the latest move by the Singaporean authorities to put a curb on individuals from spreading divisive views.

Menk has preached Muslims are not allowed to greet people of other faiths on their religious festivals, Singapore’s home affairs ministry said in a statement.

It accused Baharim of holding views that promote discord between Muslims and non-Muslims, whom he described as ‘deviant.’

“(Their views) are unacceptable in the context of Singapore’s multi-racial and multi-religious society,” the ministry said.

Reuters was not in a position to reach out to the pair.

Singapore is predominantly Chinese, many of whom follow Buddhism and Taoism but 14 percent of the population is Muslim and nearly 19 percent Christian.

Authorities in the city-state, an outpost of stability in a region where religious tension is not uncommon, are sensitive to public remarks they deem might adversely affect religious and social harmony.

Over the past few years, Singapore increased its level of surveillance for Islamist radicalism as concern grew about the spread of Islamic State in the region.

Menk and Baharim planned to conduct religious sessions on a ship departing from Singapore next month after their applications for short-term work passes to preach in Singapore were turned down, the government said.

“They will not be allowed to get around the ban by preaching instead on cruise ships which operate to and from Singapore,” the home ministry said.

Last month, authorities said they rejected applications for two foreign Christian preachers to speak in Singapore as they had made “denigrating and inflammatory comments of other religions.”
