Bangkok: Calls are growing for Australia to end its defence training and support to Myanmar's military which is accused of committing widespread atrocities against Rohingya civilians in the country's strife-torn Rakhine State.

Human rights groups have confirmed reports that Myanmar soldiers have planted internationally banned landmines along its border with Bangladesh as almost 300,000 Rohingya have fled Rakhine in the past fortnight,rapidly worsening the humanitarian crisis.

"Governments around the world who continue to train or sell arms to Myanmar's military are propping up a force that is carrying out a vicious campaign against Rohingya that amounts to crimes against humanity," said Tirana Hassan, Amnesty International's Crisis Response Director, who is at the Bangladesh-Myanmar border.

Australia agreed to further strengthen its defence ties with Myanmar's military, known as the Tatmadaw, at joint-country talks in March, after re-establishing a resident Defence Attache office in Myanmar in 2014. It has pledged $66 million in aid for Myanmar in 2017-18.
