Bombs exploded in two eastern Myanmar states leaving no casualties but damaging government infrastructure, state media said on Friday.
The blasts, hitting an electricity pylon and telephone operator office, were blamed on ethnic Karen anti-government insurgents by the New Light of Myanmar newspaper.
An electricity pylon collapsed in one explosion in Lawpita-Toungoo, Hpa-an district in Karen state at 10:40 pm local time last Sunday, the paper reported.
A door and three windows were damaged at the government-run telephone operator office in Mudon township in Mon state in another attack at 11:30 pm local time the same day, it said.
"There were no fatalities and no damage to the telephone connection," the paper said.
"Myanma Electric Power Enterprise is supplying power through Lawpita-Kalaw-Thazi power line in order not to disrupt the supply of power," the paper said.
The New Light accused the Karen National Union (KNU) of planting the bombs.
"The insurgents are committing subversive acts such as bomb explosions, planting mines with the aim of undermining the stability of the state, peace and tranquility, rule of law, killing innocent people and causing public panic," the paper said.
The KNU is the biggest ethnic rebel group in Myanmar and has been fighting for autonomy from the military regime, who have run Myanmar since 1962, for more than five decades.
Myanmar faces scores of organised resistance groups. Such small explosions are usually blamed on ethnic rebels or exiled dissident groups.
