IS vows revenge as Malaysian PM defends strict terror laws
Strict security laws are crucial to fighting terrorism, Malaysia's leader warned as the Islamic State group vowed revenge over a crackdown on its members.
Prime Minister Najib Razak says the terrorism threat is "very real" and that the laws are vital to ensure Malaysia is not open to infiltration.
Opening a two-day counter-terrorism conference, Mr Najib said "the best way to uphold civil liberties is to ensure the safety of the nation".
Human rights activists have slammed a law implemented last year that revives detention without trial.
Another law approved last month that gives sweeping powers to a council led by the prime minister has also been criticised.
Police earlier said IS, also known as Daesh, had posted a video that warns of attacks over the arrest of its members.
