A woman has been injured in an explosion at the main railway station in Burma's biggest city, Rangoon. Officials said the blast happened in a toilet, but refused to give further details.
On Friday, a woman was killed by a bomb that exploded in the station toilets in the new capital, Naypyidaw, which the military government blamed on ethnic Karen rebels.
State media have also reported a bombing last week in Pyu township between Rangoon and Mandalay.
The government blames KNU for the explosion in Pyu township but KNU denies any involvment in the blast.
Insurgents from several ethnic groups in Burma are fighting the authorities for autonomy and an end to military rule.
