Tel Aviv, Sep 12 (DPA) Israel said that it would only be willing to negotiate with a new Palestinian unity government if it recognised the Jewish state's right to exist, renounced violence and accepted past interim peace deals calling for a two-state solution.

In addition, Israel made it clear Tuesday that there would be no place for negotiations until the release of Israeli soldier Gilad Shalit, held in Gaza by Hamas militants.

Seeking to end months of international isolation, Palestinian President Mahmoud Abbas announced Monday that his moderate Fatah party agreed to form a government of national unity with the ruling radical Islamist Hamas.

The new government is to replace the current Hamas-led government, which an aide to Abbas said would be dissolved by Wednesday.

A Hamas spokesperson said his movement would support negotiations between Abbas and Israel, and would not sabotage such a process, but would not recognise the Jewish state.

Abbas earlier announced that the government's political platform will be based on the so-called "Prisoners Document", which does not include an explicit clause recognising Israel's right to exist, but does call for a Palestinian state in the West Bank and Gaza.

Hamas' charter still calls for the destruction of Israel and the establishment of an Islamist state between the River Jordan and the Mediterranean Sea.
