Those accusations continued on Tuesday, with Sudan saying the UAE was responsible for an attack on Port Sudan earlier this month, Reuters news agency reported.

"The RSF is trying to show that they don't need to reach Port Sudan by land in order to be able to have an impact there," says Sudanese political analyst Kholood Khair.

One of those who fled to Port Sudan is 26-year-old Mutasim, who did not want his second name published for safety reasons.

Since Sunday, drone strikes have hit an international airport, a major power station and a hotel in Port Sudan.

Explosions have been heard in the Sudanese city of Port Sudan as a paramilitary force targeted the de-facto capital of the country's military-led government for the third consecutive day.
