PARIS: Evacuation flights are set to rescue tens of thousands of travellers stranded in the Middle East even as some airlines resumed on Tuesday a limited number of scheduled flights. The situation remains dangerous in the region, with Qatar saying it had blocked Iranian attacks on its airport, one of the major hubs in the region. The US and Israeli attacks on Iran which began on Saturday, followed by Iranian counterattacks on Gulf states and Israel, have led the closure of the airspace of a number of countries.
