The government has asked Myanmar to release detainees after protests in which seven more people were killed.

The junta reacted to international condemnation of its crackdown by claiming ousted leader Aung San Suu Kyi had accepted illegal payments.

The Thai Ministry of Foreign Affairs on Thursday called for the release of detainees in Myanmar and urged all parties to seek a peaceful solution for Myanmar and its people through dialogue.

"As a next-door neighbour sharing a long common border, with Myanmar and Thais having close interaction in many aspects, Thailand continues to follow developments in Myanmar with much concern. As with other countries, we are saddened by the loss of lives and sufferings of the people of Myanmar due to escalating violence in the country," the ministry said.

Diplomatic pressure has been building since the generals seized power on Feb 1, triggering daily protests around the country. The United Nations on Wednesday condemned the junta's increasingly violent crackdown, which has seen more than 60 killed and 2,000 arrested, with even China -- a traditional Myanmar ally -- calling for "de-escalation" and dialogue.

On Thursday saw more action against demonstrators, with six killed in central Myanmar's Myaing township.

A witness said five of them were shot in the head.
