Two bombs exploded on Sunday in military-ruled Myanmar's biggest city, witnesses said, but no casualties were immediately reported.
The witnesses, who insisted on anonymity citing fears of official reprisal, said the first blast occurred on a downtown Yangon street at around 8 pm local time (1900 IST). The second took place on another downtown street about an hour later, the witnesses said.
There was no known claim of responsibility and authorities did not immediately mention any suspects or confirm the cause of the blasts.
The first bomb damaged a car beneath which it was hidden, eyewitnesses who live in the area said. They said the other bomb was also placed under a car. No other details of either blast were available.
