AKIPRESS.COM - A member of parliament from Myanmar opposition leader Aung San Suu Kyi's party is recovering in hospital after being slashed with a machete, a party official says.

Three men attacked National League for Democracy (NLD) member Naing Ngan Lynn — who is running for a regional assembly seat in the commercial capital of Yangon — and two other people while he was campaigning on Thursday evening (local time), reports ABC.

Police detained the attackers at a police station. Their motives were not known.

"After an operation early this morning, he's in a safe condition and not in a critical condition any more. His life is not in danger," NLD spokesman Nyan Win said.

"We have no idea what are the motives for the attack and who is behind it.

"It's important to take effective legal action after investigation."

A witness said Mr Naing was slashed in the head and arm.

"One of the guys came out and started yelling at the car. He returned with two other men with machetes and attacked the people around the campaign truck," NLD campaign manager Aung Myo Oo said.
