A small group of Myanmar nationals protesting the Koh Tao murders ruling returned to the border pass next to Kanchanaburi province Wednesday morning and Thai authorities warned tourists to avoid the Three Pagodas area there.
About 20 demonstrators, residents of Myanmar's Phaya Tong Su area, showed up at the border checkpoint near the Three Pagodas pass at about 9am.
Their rally was the third in five days and the protesters continued to express dissatisfaction with the death sentences handed down by the Samui Provincial Court for two Myanmar migrant workers convicted of murdering two British backpackers on Koh Tao in September last year.
On Monday, the protesters submitted a letter demanding the release of their compatriots and a review of the investigation that led to their arrests and convictions.
Myanmar and Thai security authorities guarded their border checkpoints on Wednesday. Thai soldiers advised tourists not to approach attractions near the Three Pagodas pass.
Myanmar authorities continued to prohibit tourists from Kanchanaburi from crossing the border to Phaya Tong Su and closed their crossing there for the fifth consecutive day in the name of safety.
Demonstrators left at about 11.30pm. They said that they arrived only to seek a response to the written demand that they filed on Monday.
