Yangon: An armed group called the Kachin Independence Army (KIA) blew up a power grid post in Myanmar`s northern Shan state, state media reported on Saturday.
Friday`s explosion hit the Namhkam-Muse 66-KV power grid. The bottom of a concrete post of the power grid was damaged in the attack, Xinhua reported citing the New Light of Myanmar daily.
Another mine was found at a second concrete pole.
Authorities said damage to towers can affect electricity supply and bring more problems to the people.
An explosion in a 230-KV power grid in Shan state last week affected the power supply to Yangon`s industrial zones.
