Police have fired rubber bullets on demonstrators in Myanmar who gathered in defiance of rules imposed by the military junta, which declared the protests illegal.

Security forces in Myanmar used rubber bullets and tear gas against anti-coup protesters who rallied to defy a ban on gatherings.

Demonstrators want power restored to the deposed civilian government and freedom for the nation’s elected leader, Aung San Suu Kyi, and her allies.

Protesters took to the streets of major cities for the fourth day in a row. Police in the capital, Naypyitaw, fired rubber bullets at the demonstrators after earlier blasting them with water cannon.

The Pulitzer Prize-winning journalist Aye Min Thant, who uses the pronoun they, said that the protesters were prepared for violence. “I saw a lot of people wearing hard hats today from the sort of things that you see in construction sites, as well as a lot more people wearing sneakers,” said Thant, who added that people in Burma typically wear sandals no matter the weather.

In addition to demanding the release of Kyi and other top-level politicians,” Thant said, they were also “very vocally and publicly” asking for a new constitution to be created.

“The leaders on the ground in terms of the civil disobedience movement, their goals are largely to cripple or to completely stop the state from being able to function,” Thant said.

Coup leaders had issued decrees on Monday night, banning gatherings of more than five people in the remote capital, which was purpose-built by the previous military regime. The ban was also imposed in the largest and second-largest cities, Yangon and Mandalay, respectively. Thousands of people have been demonstrating in both places since Saturday.

The legislation bans gatherings of more than five people and imposes an 8 p.m. to 4 a.m. curfew. It was not clear if decrees were in place for other areas.

Security forces also arrested at least 27 people in Mandalay alone on Tuesday.

People in the crowd chanted “End the military dictatorship” as the water cannon was fired.

Protesters want power restored to the deposed elected government and freedom for Suu Kyi. The military detained her and other members of her National League for Democracy (NLD) when it blocked a new session of parliament from convening on February 1.
