The military council has restricted access to food and medicine in Kayah State, where the fighting is intense, the aid workers said.
In Kayah State, fighting has been going on between junta forces and PDFs since last year’s coup.
Meanwhile, the military council has used four-cut strategy and restricted access to food and medicine.
“The medicines have not yet been delivered. If the drug stores want to order the medicines, they have to report the kind and amount of medicine to police and then they can import them from the pharmacy company with a police recommendation,” said refugee aid worker.
He added that the restrictions imposed by the military council have led to a shortage of medicine for pregnant women and children.
"As a result, there is no medicine needed for refugees. Children and adults need a variety of medicines, from cough syrups to painkillers," he said.
In addition, two hospitals treating IDPs were damaged by airstrikes by the military council and were closed.
For now, the refugees have nowhere to run due to the ongoing military offensive.
In Kayah State, more than 200,000 people are hiding in shelters and refugee camps because of clashes between the military council and the local People's Defense Forces.
