JERUSALEM (AFP) - Israel and Turkey have been holding secret talks at several levels to end their diplomatic crisis, Haaretz newspaper reported on Tuesday, quoting a senior Israeli official. The report, for which there was no confirmation, said an official representing Israeli Prime Minister Benjamin Netanyahu and Feridun Sinirlioglu, undersecretary at the Turkish foreign ministry, were involved in the discussions. Talks were also being held between the Israeli and Turkish representatives on a UN panel investigating Israel's deadly raid on a Gaza-bound flotilla in May 2010 that left nine Turkish nationals dead, the paper said. The two representatives -- Israel's Yosef Ciechanover and Turkey's Ozdem Sanberk -- have been working together on the flotilla inquiry for the past several months. But they have also been onpassing messages to their respective governments and even drafted understandings to end the crisis, according to the Haaretz. "Israel is interested in the restoration of healthy and positive bilateral relations, which are in the interest of both parties," a senior Israeli official told AFP, although he declined to comment on the report. Turkish and Israeli officials previously tried to patch up the row in December, and Haaretz said they also held a second meeting in April that was not reported.
