OSLO/JERUSALEM (Reuters) -Norwegian Foreign Minister Espen Barth Eide told Reuters on Thursday he was "reasonably optimistic" some countries that had paused funding to the U.N. agency for Palestinian refugees (UNRWA) would resume payments. UNRWA on Thursday said its entire operations in the Middle East, not only in Gaza, will most likely be forced to shut down by the end of February if its funding remains suspended. "I am reasonably optimistic that we will get funding back on track," Barth Eide said in an interview.
