The UAE, which banned entry to travellers from India last month to guard against the spread of the highly contagious Indian variant has now announced that flights between the four countries will continue to allow the transport of passengers from the UAE to Bangladesh, Pakistan, Nepal and Sri Lanka.
The Gulf state's National Emergency Crisis and Disasters Management Authority (NCEMA) also said that the ban includes transit flights coming from those countries, but transit flights to those countries can continue.
UAE citizens, long-term residency holders - known as "golden visa" holders - and diplomats are not included in the ban, which comes just ahead of the Eid festival celebrating the end of Ramadan.
To enter the UAE from the four countries, people must have been in another country for at least 14 days beforehand, NCEMA said.
