A woman has been injured in a bomb blast in Burma's commercial capital, Rangoon, officials say - the third bombing incident in three days.
The latest explosion occurred at a public toilet in a Rangoon railway station, witnesses said.
On Friday, a woman was killed by a blast in a railway station toilet in Nay Pyi Taw, the new capital.
And another man died, and four people were injured, when a bomb exploded in Pyu, north of Rangoon.
The government has blamed both incidents on the Karen National Union (KNU), a group fighting for greater autonomy for the ethnic Karen people.
The state-run newspaper, the New Light of Myanmar, said in both cases it was the bomber who was killed in the process of handling the bomb.
There was no claim of responsibility from the KNU or any other group.
