A Rohingya Muslim woman reportedly had her leg blown off by a landmine as she fled Burma for Bangladesh.

"They are putting the landmines in their territory along the barbed-wire fence," the source said.

They added: "Our forces have also seen three to four groups working near the barbed wire fence, putting something into the ground.

"We then confirmed with our informers that they were laying land mines."

One of the reported victims was a woman whose leg was mutilated as she tried to cross the border.

Earlier this week, a Bangladesh border guard told Reuters one boy had his leg blown off near a border crossing before being brought to Bangladesh for treatment, while another boy suffered minor injuries.

About 164,000 Rohingya from the area have fled across the border into Bangladesh in less than two weeks since Rohingya insurgents attacked police outposts in Gawdu Zara and several other villages, the UN refugee agency said.

The military has said nearly 400 people, most they described as insurgents, had died in clashes and that troops were conducting "clearance operations." It blames insurgents for setting the villages on fire, without offering proof.

The Rohingya who have fled Burma, however, all described large-scale violence perpetrated by Burmese troops and Buddhist mobs — setting fire to their homes, spraying bullets indiscriminately, stabbing civilians and ordering them to abandon their homes or be killed.

Burning Rohingya homes can make it less likely that they return.

Tens of thousands of Rohingya were driven from their homes in another wave of violence in 2012. Many of them are now confined to camps, while the land they once held is either vacant or occupied by Buddhist squatters.

Burma refers to Rohingya as Bengalis, contending they migrated illegally from Bangladesh, although many Rohingya families have lived in Burma for generations.

With so many Rohingya fleeing Burma, it's unclear how many remain.

Before the recent violence, aid experts had estimated about one million Rohingya were living in northern Rakhine state, but aid agencies have been unable to access the area since.
