Since the violent takeover of the Gaza Strip by Islamist Group Hamas in mid-June, which left Abbas in control of only the West Bank, the president and his Fatah party have received the backing of Israel, moderate Arab states, and western nations.
"No elections will be held in the Palestinian Authority before the Palestinian homeland is unified," the Israeli Ynet news portal quoted Abbas as saying after a joint news conference with Austrian Chancellor Alfred Gusenbauer in Ramallah, in the West Bank.
On Sunday, Abbas introduced amendments to election laws that were widely seen as obstacles to Hamas's future participation in elections.
Hamas, which won a majority of seats in parliament in January 2006 elections, has said it would be unconstitutional for Abbas to call early parliamentary and presidential elections, and has threatened to block the initiative.
Palestinian parliamentary elections are not scheduled until 2010, and the current interim constitution has no provisions for calling early polls.
Abbas earlier announced he was considering the possibility of early legislative elections in the Palestinian territories. However, he said then that elections would be held only following the reunification of the West Bank and the Gaza Strip.
