Israeli and Qatari officials are set to meet in Norway in an effort to revive talks about the release of hostages held in Gaza in return for a ceasefire and the freeing of Palestinian prisoners held by Israel, Reuters reports, citing a report by the Wall Street Journal.

Qatari Prime Minister Mohammed bin Abdulrahman Al Thani was due to meet David Barnea, director of Israel’s Mossad intelligence agency, in Oslo, the report added, citing people familiar with the matter. Barnea is also likely to meet with Egyptian officials, WSJ reported.

Significant obstacles impede a resumption of negotiations on a new hostage deal including disagreements over the possible terms within Hamas, the report added, citing people familiar with the talks.
