BEIRUT (Reuters) - Lebanon’s caretaker foreign minister escalated his row with the U.N. refugee agency UNHCR on Wednesday, accusing it at a news conference of working to stop refugees from returning to Syria.

UNHCR has denied the accusation, saying it supports the return of refugees when it is safe for them to go back to Syria and helps those who choose to return with their documentation.

“Their policy is to forbid the return,” Foreign Minister Gebran Bassil said. “The Lebanese policy is to encourage the return. Forbid, encourage. Stop, facilitate. That’s it,” Bassil said during the news conference in the town of Arsal, where he spoke alongside Syrian refugees.

“UNHCR does not forbid refugees from returning,” Rula Amin, UNHCR’s MENA region spokesperson sad in emailed comments to Reuters. “UNHCR’s policy is clear on this matter: we respect people’s free choices to return.”

“UNHCR is not the obstacle to the return, the obstacles lay elsewhere and in the complex situation on the ground,” Amin said, adding that the UNHCR recognizes the challenges Lebanon faces in hosting Syrian refugees.

As Syrian forces and their allies retake more territory, Lebanon’s president and other politicians have increasingly called for refugees to go back to “secure areas” before a deal is reached to end the war. The international view is that it would not be safe for them to return yet.

The U.N. has registered about a million refugees in Lebanon - nearly a quarter of Lebanon’s population. The Lebanese government, which puts the figure at 1.5 million, says it wants them to start going back to territory where fighting is over.

Bassil said on Wednesday the burden of hosting Syrian refugees seven years into the conflict that drove them to flee had grown “unbearable”, blaming the crisis for the collapse of the economy and emigration of Lebanese citizens.

Last week, Bassil ordered a freeze on applications by the U.N. High Commissioner for Refugees (UNHCR) for residency permits for its staff, saying it was intimidating refugees into staying in Lebanon.

Some 19 UNHCR staff members are affected by the Lebanese residency permit freeze, UNHCR Lebanon representative, Mireille Girard, told Reuters on Tuesday, and the agency’s spokesman in Geneva said it hopes the decision will be reversed.

Bassil accuses UNHCR of discouraging refugees from going home by asking them questions about potential difficulties they face upon return, including possible military conscription, damage to housing and lack of U.N. support in parts of Syria.

“I don’t want to have disputes with them, but it’s time to tell them enough,” he said.

The UNHCR favors the return of all refugees when it is safe for them to go home and speaks to refugees in all countries when they are preparing to return home to make sure it can give them enough support and protection, Girard said.

“We understand, Lebanon cannot accommodate such a large population,” UNHCR head Filippo Grandi said at a press conference in Geneva.

“We say: ‘Be patient, because returns will be limited by conditions in Syria’. And at the same time, we say to donor countries: ‘You must do more for Lebanon. Not only regarding refugees, but also for the communities who are accommodating these people,” Grandi said.

Another senior U.N. official, the deputy special coordinator for Lebanon Philippe Lazzarini, said the U.N. shares Lebanon’s view that refugees’ stay in Lebanon should be temporary, but he said they need to be able to return safely.

“The U.N. has and will continue to respect individual decisions of refugees to return home,” he told Reuters.
