The army has been deployed to help with rescue efforts in the affected hill region of Chittagong, said the region's chief administrator, Sirajul Haq Khan, who warned that the death toll could rise as more remote areas are accessed.

According to Khan, at least 94 people died in a series of landslides and flash floods in and around Chittagong port and the neighbouring districts of Cox's Bazar and Bandarban.

Bandarban administrator Tariqul Islam said 36 bodies have been recovered from multiple landslide sites.

"Rescue efforts had been hampered as communications have been largely snapped because of flash floods and heavy rain," Islam told AFP.

"Ten of the victims were children and scores of others were injured," he said.

In neighbouring Bandarban district, 25 bodies have been recovered from multiple landslide sites, local police chief Saiful Ahmed said.

“One family has lost 12 members,” Ahmed told AFP, adding that rescue operations had been delayed by heavy monsoon rains.

Chittagong port received 40 centimeters of rain in a single 12-hour period on Tuesday.

Flights in and out of Chittagong’s Shah Amanat International Airport have been suspended since Tuesday afternoon.

Train links between Chittagong and the rest of the country were also severed after a railway bridge collapsed due to a rain-triggered flash flood.

In recent years monsoon rains have caused deadly landslides in Chittagong, home to five million people, killing hundreds and prompting the government to tighten rules on where development can take place. AFP
