Five bomb blasts took place in quick succession in Muse town on Myanmar's northeastern border Saturday midnight but there were no reports of any casualties, Xinhua reported Sunday.
The loud explosions occurred on the central line of the Union Highway where there were some dumps.
The explosions took place at a time when there was less traffic. It was not clear who or what caused them.
Muse town is in the northeastern Shan state where major trade routes are present.
In April, a bomb went off at a border checkpoint, killing an immigration officer.
