Myanmar's military is continuing its crackdown on civilians protesting the February 1 coup in the country.
A human rights group said 536 people have been killed in clashes with security forces.
In the largest city of Yangon, young protesters marched in the streets, chanting anti-military slogans.
On Wednesday night, the military announced that it will observe a unilateral one-month ceasefire from April 1 unless it is again attacked by ethnic armed forces.
The military had been conducting airstrikes on the forces, which joined demonstrators protesting the military.
The forces have yet to officially respond to the announcement. But they say they intend to protect civilians, and seem ready to continue their offensive unless the military stops its crackdown.
Local media say a military operation in the second largest city of Mandalay on Thursday resulted in injuries to demonstrators.
