Israeli and Turkish diplomats are still seeking a formula whereby the two countries can find a way to put the Gaza flotilla crisis behind them.
The United Nations report on the 2010 flotilla - expected to justify Israel's actions to a large degree - is to be published this weekend. After its release, it will be extremely difficult to reach a compromise.
The UN commission, headed by former New Zealand prime minister Geoffrey Palmer and appointed by UN Secretary General Ban Ki-Moon, completed its report four months ago but publication has been postponed three times.
Diplomats who have seen the report have said that it justifies Israel's decision to block the flotilla to Gaza in May 2010, although it does criticise the degree of force used by Israeli naval commandos in the violent confrontation on the Marmara ferry in which nine Turkish activists were killed.
