Fighting erupted in eastern Myanmar near the Thai border early on Tuesday as ethnic minority Karen insurgents attacked an army outpost in some of the most intense clashes since a Feb. 1 coup plunged Myanmar into crisis.

The clash came as the junta, in an apparent set-back for an attempt by the Association of Southeast Asian Nations (ASEAN) to end Myanmar's turmoil, said it would "positively" consider the bloc's suggestions made at a weekend meeting in Indonesia.

Southeast Asian leaders said over the weekend they had reached a consensus with the junta on steps to end violence and promote dialogue between the rival Myanmar sides.
