Manila: A radio journalist was gunned down as he hosted a singing contest in the southern Philippines on Monday.

Desidario Camangyan of Sunshine FM radio died from a gunshot wound to the head on Monday night in the gymnasium of Davao Oriental province's Manay township, said Inspector Ariel Nueva, the town's police chief.

Camangyan, 52, was sitting on stage in front of a crowd of spectators, when the attacker shot him from behind.

The gunman escaped on foot. Police were Tuesday trying to determine his motive. There's speculation that the attack was related to Camangyan's work as a broadcaster.

The Philippines prides itself on having the most liberal media in Southeast Asia, but it's also among the world's most dangerous places for journalists.

In the world's deadliest single assault on media workers, at least 30 reporters were among the 57 people massacred on November 30 last year, in the southern Philippines. The victims were in a vehicle convoy which got caught up in political riot. A total of 75 media workers had already been killed in the country since 2001, according to the International Federation of Journalists.
