Here is a video report on two churches in Malaysia that were "firebombed" by Muslims that were angry over the word "Allah" being used by non-Muslims.
Christian Churches in Malaysia are on "high alert" as a result of the bombings.
NOTE: The Bible translated into the Malay Language uses the word "Allah" for God. That has been the case since the early 1800's. So the Christians use of "Allah" for God is totally consistent with the reading of the Bible in their own language.
