Three small explosive devices were fired with a home-made grenade launcher at the Myanmar Plaza branch of Harry’s Bar on Monday evening.

A resistance group called Special Task Agency of Burma-STA claimed responsibility.

According to a spokesperson for the group, the waiters were told beforehand to quietly tell the patrons to leave.

“As a result, no one got injured, but only bar tables and glasses were damaged," he said.

One of the explosive devices failed to explode.

A shopkeeper said after the explosion, a number of junta soldiers visited the scene.

Harry’s Bar is reportedly owned by a shareholder of the Htoo group of companies run by Myanmar businessman Tay Za.

Myanmar Plaza, one of Myanmar’s most popular shopping malls, suffered from a months-long boycott after private security staff violently detained young protesters inside the mall in November last year.

Since an anti-holiday campaign by resistance groups in Myanmar was announced, Military Council raids have picked up pace.
