Protests against the military coup showed no sign of abating with more planned across the country, as Southeast Asian neighbors struggled for consensus in their efforts to end the month-long crisis.
Video obtained by Reuters showed protesters using the fire extinguishers as well as smoke grenades as they retreated after shots were heard in Sanchaung in Yangon.
Meanwhile, Myanmar security forces and protesters faced off in Mandalay, with protesters using a fire extinguisher to create cover and throwing objects towards police.
At least 21 people have been killed since the Feb. 1 coup against Aung San Suu Kyi's democratically elected government.
The Association of Southeast Asian Nations (ASEAN) failed to make any breakthrough in a virtual meeting on Myanmar by its 10 foreign ministers. While they were united over call for restraint, only four members - Indonesia, Malaysia, the Philippines and Singapore - called for the release of detainees including Suu Kyi.
