A church in Malaysia has been vandalised in the latest attack triggered by the simmering row over the use of the word "Allah".

Windows of the two-storey church in southern Negeri Sembilan state, on the Malay peninsula, were found to have been smashed late on Friday, David Raju, the spokesman for the Grace Global Prayer Church, said on Saturday.

"I think this is part of an attack on churches in the country," Raju told the AFP news agency.

"Somebody used a thick iron rod to smash the thick glass," he said. Police were investigating the incident.

The attack is the eleventh against a church since the High Court ruled in favour of allowing the Catholic Church's Herald newspaper to use "Allah" in its Malay-language section as a translation for "God".

Mosque incident

In another incident, on the island of Borneo, police confirmed reports that they had found broken glass of what was reported to have been a rum bottle outside a mosque in Kota Samarahan, in Sarawak state.

"Broken glass was found outside a mosque. We are investigating. I do not want to say anything more," Ismail Omar, the deputy inspector of police, told AFP.

The Malaysian government has strongly criticised the attacks on churches, but has been accused of stoking Malay nationalism to protect its voter base after the opposition made unprecedented gains in 2008 elections.

In Geneva, the World Council of Churches said it was disturbed by the attacks and called on the Malaysian government to take immediate action.

About nine per cent of Malaysia's 28 million people are Christian, including 850,000 Catholics, most of whom come from indigenous groups in the Borneo states of Sabah and Sarawak.
