Prime Minister Benjamin Netanyahu told Greek Prime Minister George Papandreou yesterday that he is very worried over recent developments in Turkey and increasing extremism in that country.

President Shimon Peres told Papandreou when the two met on Wednesday that Israel wanted to restore its good relations with Turkey, but did not understand what happened to relations and what Turkey had against it. Papandreou and Netanyahu met privately, after which their advisers joined them for lunch at the prime minister's residence in Jerusalem.

The Turkish issue was central in talks between Papandreou and Netanyahu. The two leaders also discussed the situation in Gaza. Netanyahu told Papandreou about the steps Israel has taken to ease the blockade on Gaza and that there was now no need for additional aid flotillas to the Gaza Strip.

Papandreou said he welcomed the lifting of the blockade but Israel should do more to improve the humanitarian situation in the Gaza Strip.

Papandreou also met yesterday with Foreign Minister Avigdor Lieberman and opposition leader MK Tzipi Livni (Kadima ).

He also visited the Yad Vashem Holocaust memorial and planted a tree in the Grove of Nations, a forest near Yad Vashem where world leaders plant trees symbolizing peace.
