The "vast majority" of players who were stranded in Dubai following last week's men's tennis tournament in the Emirates have been able to leave the UAE, the ATP announced on Wednesday.
Several high-profile players, including champion Daniil Medvedev, were unable to leave the country following the start of Israel and the United States' war with Iran.
"The vast majority of players who were in Dubai have successfully departed today on selected flights," the ATP said.
"The safety and wellbeing of our players, support teams and staff members remains our highest priority, and we continue to remain in close contact with those affected."
Russian media reports said Medvedev and his compatriots Andrey Rublev and Karen Khachanov had been able to leave Dubai via Oman on Tuesday.
They were then due to head to Istanbul before flying to the United States, where the ATP/WTA 1000 Indian Wells tournament starts later on Wednesday.
As all three players are seeded for that event they will not play until the second round, which runs Friday and Saturday.
Finnish player Harri Heliovaara, who won the Dubai doubles title alongside Britain's Henry Patten, said in a blog post he had managed to reach Italy.
"We got on the flight to Milan, and as I write this, we are in Italian airspace," said Heliovaara.
"We will probably get to Finland on Wednesday evening."
A second-tier ATP Challenger tournament in another Emirati city Fujairah was cancelled on Tuesday after drone strikes on nearby oil refineries.
The ATP said it was "in close contact with the tournament organisers to support the players present at the venue".
"Accommodation and essential needs remain provided by the tournament and a charter flight has been arranged and 100 per cent funded for the ATP to participate in their departures from the region at no cost to the players," the statement added.
The US and Israel triggered the rapidly spreading war on Saturday with a strike on Tehran that killed supreme leader Ayatollah Ali Khamenei and several more senior figures, followed by days of air and missile raids aimed at weakening the remaining government.
Iran's armed forces responded with missile and drone attacks on Israel, US embassies and military bases and on its Arab neighbours around the Gulf.
