Walid Muallem called the line nonnegotiable for Syria and said future talks regarding the Golan Heights must deal with these "decisive and important" border issues, The Jerusalem Post reported Friday.

Druse leader Walid Jumblatt, meanwhile, has accused Syrian President Bashar Assad of using the indirect talks with Israel to strengthen diplomatic ties between Syria and the United States, the Post reported.

Jumblatt attacked Thursday's four-way summit in Damascus saying the meeting between leaders of Syria, France, Turkey and Qatar violated the Arab initiative for peace with Israel, the Post reported.
