Two bombs exploded at a Myanmar hotel golf course on Saturday, wounding two people during a tournament to mark next week's Armed Forces Day, a government official said.
The first blast occurred at around 7:00 am at the Regina Hotel golf course in Tachilek, near the border with northern Thailand, followed an hour a later by a second explosion, the official, who did not want to be named, told AFP.
Two people were wounded by the second bomb and sent to hospital in Thailand, he said.
"The blasts occurred at the golf course while it was holding a golf tournament for the upcoming Armed Forces Day. The second blast occurred while the security personnel were cleaning the area," the official said.
It was unclear whether the wounded were military personnel.
Armed Forces Day on March 27 marks the day in 1945 when the army rose up against occupying Japanese forces.
Myanmar has been hit by several bomb blasts in recent years, most of them minor, which the authorities have blamed on armed exile groups or ethnic minority fighters.
The new government, which took power last year ending five decades of military rule, has signed peace deals with several rebel groups in an effort to end a civil war that has gripped parts of Myanmar since independence in 1948.
An end to the conflicts and alleged rights abuses by troops is a key demand of Western nations which have imposed sanctions on the country.
In April 2010, in the worst attack in five years in Myanmar's main city Yangon, a series of blasts left 10 people dead and about 170 wounded as thousands of people gathered for festivities to mark the Buddhist New Year.
