The head of the International Monetary Fund's department in Europe says Greece's bailout talks have gathered "a little more momentum" but stressed that Athens remains under pressure to break the deadlock with lenders.

Poul Thomsen told German business daily Handelsblatt in an interview published Monday that Greece could have enough money to meet debt and other commitments until June but would need to reach an agreement before then.

Thomsen, who led most of Greece's bailout inspections before taking up his current post, said the two sides needed to make "significantly more" progress.

Bailout lenders are at odds with Greece's new left-wing government over reforms, including sweeping changes to pensions and labor rules.

Greece will top discussions Friday at a meeting of the finance ministers from the 19-country eurozone.
