Myanmar's government has said it is not responsible for the migrant boat crisis in south-east Asia, and may not attend an emergency summit on the issue, the BBC reported on Sunday.

Thousands of migrants from Bangladesh and Myanmar are feared stranded in boats in the Andaman Sea after their crews deserted them.

Indonesia, Malaysia and Thailand have been turning away migrant boats.

Survivors have described desperate conditions on the boats, with people thrown overboard amid fights for food.

Rohingya Muslims have been leaving Buddhist-majority Myanmar, also known as Burma, because they are not recognized as citizens and face persecution.

Many of the Bangladeshis at sea are thought to be economic migrants.

However, Zaw Htay, director of Myanmar's presidential office, said his leaders would not attend if the word "Rohingya" was used in the invitation, as they did not recognize the term.
