Jaafari, who submitted the proposals to Special UN Envoy for Syria Staffan de Mistura, requested the envoy to discuss these proposals with opposition members involved in intra-Syrian negotiations underway in Geneva.
"Another point [of the Basic Proposals] is that we call through the Special Envoy on all of us, the government's delegation and delegations of the oppositions, to engage into a clear-cut commitment to liberating our occupied territories — the Syrian occupied Golan [Heights], back to the borders of June 1967," Jaafari said.
The Golan Heights is a disputable Middle Eastern territory, which was a part of Syria before 1967. During the 1967 Six-Day War, Israel seized the Golan Heights.
Syria demands from Israel to fully withdraw to the pre-1967 border, however Israel is unwilling to accept these terms as it will give Syria access to the Sea of Galilee, which is Israel's main source of fresh water.
Syria has been mired in civil war since March 2011, with government forces loyal to Syrian President Bashar Assad fighting numerous opposition factions and extremist groups.
The current round of the intra-Syrian talks aimed at putting an end to the five-year civil war is underway in Geneva and will wrap up on March 24.
