YANGON, Aug. 1 (Xinhua) -- The Myanmar authorities warned on Friday against more bomb attacks following Wednesday's mine explosion in northeastern Kayin state and urging people in the country to remain vigilant against more such probability, official media reported.

    The mine explosion in the state's Leiktho, Hpa-an at night caused collapse of and damage to a pylon located between the areas of Lawpyita and Toungoo, said the New Light of Myanmar.

    The authorities blamed the country's largest anti-government ethnic armed group, the Kayin National Union (KNU), responsible for the incident.

    According to the report, Myanmar's state-run Electric Power Enterprise is regularly supplying power through Lawpita-Kalaw-Thazi power line in order not to disrupt the power supply.

    The authorities also appealed to the public to come forward timely with information about the terrorists.

    On Dec. 18 last year, about seven members of the KNU detonated a mine and fired small arms at a passenger bus which was on its way to Myawaddy from Kawkareik in the border area with Thailand in the same state, killing eight people and wounding six others, according to earlier official report.

    The authorities charged the KNU with constantly committing all destructive acts such as undermining stability of the state, community peace and tranquility and prevalence of law and order.

    Since the government adopted a policy of national reconciliation in 1989, 17 main anti-government armed groups have made peace with the government under respective cease-fire agreements and leaving the largest of them, the KNU, out of the legal fold.
