Attackers fire-bombed a Malaysian church and tried to set another ablaze Friday amid a growing conflict over the use of the word "Allah" by non-Muslims, the Associated Press reports.

The attacks sharply escalated tensions in the Muslim-majority country ahead of planned protests later Friday against a Kuala Lumpur High Court verdict which struck down a 3-year-old ban on non-Muslims using "Allah" in their literature, according to the AP.

The Dec. 31 court decision incensed many Muslims, who see it as a threat to their religion. Hateful comments and threats against Christians have been posted widely on the Internet, but this is the first time the controversy has turned destructive.

The ruling was on a petition by the Herald, the main publication of Malaysia's Roman Catholic Church, which uses the word Allah in its Malay-language edition.

Only the first floor office in the three-story Metro Tabernacle Church was destroyed in the pre-dawn blaze, said Kevin Ang, a spokesman for the Protestant church. The worship areas on the upper two floors were undamaged and there were no injuries.

He quoted a witness as saying she saw three or four men on a motorcycle break the main glass front of the church and throw a gasoline bomb inside. The church occupies a corner plot in a row of shops in Desa Melawati, a suburb of Kuala Lumpur.

Separately, a Molotov cocktail was thrown into the compound of a Roman Catholic church before dawn Friday but caused no damage or injuries, said the Rev. Lawrence Andrew, the editor of the Herald.
