Five separate bombs exploded on Wednesday night in Hlaing Tharyar Township in Rangoon, but no one was injured, said sources in Rangoon.
The first blast reportedly occurred at about 9 p.m. inside a factory owned by UMW, a private construction equipment company. While police were investigating the scene, two bombs exploded nearby at about 11 p.m., close to the Valiant (V) cigarette factory. Another twin explosion occurred an hour later near the Max Soft Drink Company.
Local military authorities quickly deployed more security guards in the Zone 5 area where the explosions occurred and informed all residents in Hlaing Tharyar to report all guests to the authorities.
It is not clear who is behind the bomb blasts and an investigation by Burmese police is under way.
Police officials in Hlaing Tharyar confirmed the five explosions but would make no further comment, saying the matter is under investigation.
The Burmese military government regularly accuses armed ethnic groups and dissidents in exile of responsibility for bomb attacks.
