KUALA LUMPUR, Malaysia (AP) – Firebombs were thrown at two more churches in Malaysia early Sunday, the latest in a series of assaults on Christian houses of worship following a court decision that allows non-Muslims to use “Allah” to refer to God.

Hundreds of worshippers whose parish church was partly gutted in the firebomb attack last week gathered at a makeshift prayer hall for their Sunday service and called for national unity and an end to violence. On Sunday, a Molotov cocktail was hurled at the All Saints Church in Taiping town in central Perak state early in the morning before it had opened, said state police chief Zulkifli Abdullah.

He told The Associated Press that the building was not damaged but police found burn marks on the wall. A broken kerosene bottle with an unlit wick was found early Sunday inside the compound of the St. Louis Catholic church, also in Taiping, said the Rev. David Lourdes.

He said it appears to be a failed attack. Four churches were hit by gasoline bombs on Friday and Saturday. The dispute is over a Dec. 31 High Court decision that overturned a government order banning non-Muslims from using the word “Allah” in their prayers and literature.
