Security officials in Burma say five explosions have rattled the city of Rangoon. Witnesses say at least one of the blasts detonated outside a post office, shattering its windows.
Other explosions occurred near electricity transformers in the center of the city around 2 A.M. local time Thursday. No injuries were reported and the cause of the blasts was not immediately known.
Rangoon has seen a spate of bombings for more than a year. Twenty three people were killed last May in explosions at two shopping malls and a convention center. The military government often blames ethnic minority rebels or foreign opposition groups for the violence.
Some dissidents say the blasts are carried out by government-linked groups to justify tighter security.
