A church and Christian newspaper in Malaysia are suing the government after it decreed that the word "Allah" can only be used by Muslims.

In the Malay language "Allah" is used to mean any god, and Christians say they have used the term for centuries.

Opponents of the ban say it is unconstitutional and unreasonable.

It is the latest in a series of religious rows in largely Muslim Malaysia, where minority groups claim their rights are being eroded.

Muslims must have an interesting view of intellectual property.
