The two middle-aged men had lunch at the shop on Tuesday and left behind a packet that later exploded, the Burmese-language Myanma Ahlin daily newspaper reported. A waiter was slightly wounded in the blast, but no damage was caused to the two-story wooden building.

The shop is owned by a French citizen who sells lacquerware and silk. Police cordoned off the premises and closed down a nearby market popular with tourists where a festival was taking place, witnesses said.

Police declined to comment on the case. No one claimed responsibility for the blast, Rangoon’s third this year.

In June, four bombs exploded near the central railway station. No casualties or damage were reported and no group claimed responsibility. Rangoon blamed exiled dissidents in Thailand.

In November, a small explosion occurred in front of a government court complex, causing minor damage but no injuries. No one claimed responsibility.

Public dissent is rare in the tightly guarded capital, and anti-government violence even more uncommon, although there is a well-organized armed opposition to the government along Burma’s eastern border with Thailand.
