Bangladesh has summoned the Myanmar ambassador in Dhaka to protest against the planting of landmines along the border between the two countries.
It comes amid growing tensions over the huge influx of Rohingya Muslims fleeing violence in Myanmar.
A senior official in Bangladesh said they believed Myanmar government forces were planting the landmines to stop the Rohingya returning to their villages.
But a Myanmar military source said no landmines had been planted recently.
The BBC’s Sanjoy Majumder, who is on the Bangladeshi side of the border, said there had been at least three injuries caused by landmines this week.
When asked whether Bangladesh had lodged a complaint about the mines, Foreign Secretary Shahidul Haque said “yes” but did not elaborate further.
The UN has said the number of Rohingya refugees crossing from Myanmar into Bangladesh has surged since 25 August.
It says more than 146,000 Rohingya have fled violence in Myanmar’s Rakhine state, in the northwest of the country.
The conflict was triggered by an attack by Rohingya militants on police posts.
Following the attack there was an outbreak of violence which has sent waves of refugees fleeing the country, also called Burma. – BBC
