Burma's military aircraft have been targeting rebel areas in country's northern Kachin state over the last five days, video footage has revealed.
The footage, obtained by the BBC, which was shot by humanitarian group Free Burma Rangers, shows attack helicopters firing on the ground and jets flying close to the trenches of the rebel Kachin Independence Army.
A government official said the army had not informed them of any air attacks. Fighting with the Kachin rebels resumed in 2011, after a 17-year truce.
The presence of jets and attack helicopters in recent days was also confirmed by witnesses in the area.
According to the report, it is not clear how many casualties have been caused in five days of air attacks.
Many of the people who live in the conflict areas have already fled into camps, both in Kachin and across the border in China.
Asked to comment on the video, the director of the president's office, Zaw Htay, said the situation was complex, and that the military had told them they were only using planes to re-supply its troops, the report said.
He added that they wanted to hold peace talks with the rebels as soon as possible, the report added. (ANI)
