GREECE TALKS: Greece and its creditors continue to hold meetings to reach a new bailout deal for the country. Greece needs loans in time to make a debt payment on June 30. The sides appeared to be moving closer to an agreement this week, but on Wednesday it became clear that some differences remain on what reforms Greece should make in exchange for loans.

German Finance Ministry spokesman Martin Jaeger said his delegation was heading to a meeting on Greece with "realistic expectations" and its impression was that plenty of work remains to be done.

Greek stocks fell 2 percent. Germany's DAX fell 0.4 percent, France's CAC 40 was flat and the U.K.'s FTSE 100 was up 0.3 percent.
