An increasing number of attacks targeting the military and police in Myanmar have occurred after the country's pro-democracy forces issued a call for a revolt against military rule.
The National Unity Government declared the launch of a "defensive war" against the military junta in an online speech on Tuesday. Myanmar has been in continued unrest since the military seized power in February.
The NUG acting president noted in the speech that the military continues to carry out killings, torture and detention.
Video footage from local media said to be taken in the central city of Monywa on Thursday shows an explosion near a security unit on the roadside.
A local armed group reportedly claimed responsibility for the attack, saying they killed one security trooper and injured two others.
Local media reported several facilities owned by a military-related cell network company were attacked in the northwestern region of Sagaing and central region of Magway. A series of explosions have also been reported in the country's largest city of Yangon.
A human rights group in Myanmar estimates 1,054 people have been killed in the country through Wednesday after the military crackdown following the coup.
