Several Myanmar military aircraft fighting rebels have crossed the border into Bangladesh and opened fire in Bandarban, causing panic among local residents, reports bdnews24.com.
The incident occurred on Saturday, only five days after two mortar shells from the military-ruled country also crossed the border amid the ongoing crackdown on seditious elements in the country.
The two fighter jets and helicopters were attacking rebels in neighbouring Rakhine state when some of the shells fell in the Ghumdhum area of Naikhyangchhari Upazila on Saturday.
"The warplanes passed the area between border pillars 40 and 41 under the surveillance of Reju Amtali (Border Observation Post) in Ghumdhum around 9:20 am," said Tariqul Islam, the district's superintendent of police.
On Wednesday, the rebel Arakan Army killed 19 junta police officers when it seized a police outpost in Maungdaw Township near the border, according to the Irrawaddy, a news site founded by Burmese exiles living in Thailand.
They also took firearms, ammunition and other equipment.
In response, the Myanmar regime conducted airstrikes in the region and moved to retake it, according to the report.
Previously, the Bangladesh government lodged a strong protest after two mortar shells fired from Myanmar fell into Bangladesh on Aug 28.
The warplanes involved in the airstrikes on Saturday fired as many as 10 shells, while the helicopters fired at least 35 rounds of bullets.
UNB adds: Law enforcement agencies have further strengthened security measures along Bangladesh-Myanmar border at Naikhongchhari point as locals reported firing from helicopters from the Myanmar side on Saturday, says an official.
For last few days tension has been growing along the Myanmar border with Bangladesh which has also spread among locals at Naikhongchhari and Ghumdhum border areas, said Md Tariqul Islam, Superintendent of Bandarban police.
"Today locals have reported spotting firing from a Myanmar helicopter near the border and two mortar shells dropped from it", he said
The law enforcement agencies including Border Guard Bangladesh (BGB) remains alert and intelligence surveillance has also been increased near the Bangladesh-Myanmar border, said SP Tariqul Islam.
On Thursday, State Minister for Foreign Affairs Md Shahriar Alam said Bangladesh is better prepared so that none can enter from Myanmar now due to the deteriorated situation in Rakhine state.
The Myanmar side was warned twice in August following mortar shells landing in Bangladesh territory from Myanmar and strong protest was lodged in this regard.
"We do not want to step into Myanmar's provocation or trap," he said, adding that they (Myanmar side) might have a strategic benefit if they can move in such a unilateral direction.
The Ministry of Foreign Affairs last Monday summoned Myanmar Ambassador to Bangladesh Aung Kyaw Moe and lodged a strong protest against Myanmar's mortar shells landing inside Bangladesh territory a day earlier.
