Bangladesh's foreign minister has dismissed speculation that the chief of Myanmar's Arakan Army is receiving medical treatment in Bangladesh, as intensifying fighting across the border fuels security concerns and fears of another Rohingya influx.

Speaking to reporters at the Ministry of Foreign Affairs on Sunday, Foreign Minister Dr. Khalilur Rahman said the government had no information regarding the reported presence of the Arakan Army leader in Bangladesh.

"I have no information on this matter," he said when asked about the reports.

His remarks came as Myanmar's military steps up operations against the Arakan Army in Rakhine State, particularly in areas near the Bangladesh border, including Maungdaw and Buthidaung.

Residents in Bangladesh's border town of Teknaf have reported hearing heavy explosions and prolonged gunfire from across the frontier in recent days, with some saying the blasts shook their homes.

The escalating conflict has raised concerns in Bangladesh over border security and the possibility of another wave of Rohingya refugees fleeing the violence. Unconfirmed reports suggested that hundreds of Rohingya had gathered near the Naf River seeking to enter Bangladesh, prompting the Border Guard Bangladesh (BGB) to strengthen patrols and maintain heightened vigilance along vulnerable sections of the border.

Addressing the deteriorating security situation, Khalilur Rahman said the government is closely monitoring developments.

"We are monitoring the border situation. We have increased surveillance along the border," he said.

The latest escalation underscores the growing regional impact of the Myanmar conflict, with fighting between the military and the Arakan Army increasingly spilling over into communities along Bangladesh's southeastern frontier.
