GAZA, Sept. 13 (Xinhua) -- A national conference participated by Palestinian factions in the Gaza Strip on Thursday called for annulling the transitional Oslo Peace Accords signed in 1993 between Israel and Palestine Liberation Organization (PLO).

Islamic Hamas movement, the Islamic Jihad (Holy War) movement, the Popular Front for the Liberation of Palestine (PFLP), the Democratic Front (DFLP) and other minor groups organized the conference under the title "unity and resistance are our option."

Deputy Hamas Chief in Gaza, Khalil al-Hayyah, told the conference that Oslo Accords "brought catastrophic results to the Palestinians and their cause, enabling Israel to boost its military occupation of the Palestinian territories."

He called on the Palestinian Authority (PA) to withdraw from the agreement "because we paid heady and painful price for it," declaring that the accords and all its outcomes "are annulled."

Al-Hayyah also called on the Palestinian factions and powers "to reach a comprehensive national unity agreement that includes the reconstruction of the Palestinian establishments and save all the efforts to resist the occupation."

Meanwhile, Mohamed al-Hindi, a senior Islamic Jihad leader in Gaza said that "the final result of Oslo Accords was a complete failure and a threat to destroy the entire Palestinian cause."

Oslo Peace Accords was signed between Israel and the PLO at the White House on September 13, 1993, in an effort to end decades of conflict, which included a declaration of principles on establishing an autonomous authority as part of the interim government.

Under the agreement, the Palestinians would establish a self-governing authority, return hundreds of thousands of Palestinians to the West Bank and Gaza, build state institutions and improve the standard of living of the Palestinian citizens.

After 25 years, the agreement hasn't ensured a final peace agreement nor the establishment of an independent Palestinian state.
