Palestinian officials threatened Sunday to withdraw from key provisions of the Oslo Accords, which define relations with Israel, if US President Donald Trump announces his Middle East peace plan next week. Chief Palestinian negotiator Saeb Erekat told AFP that the Palestine Liberation Organisation reserved the right “to withdraw from the interim agreement” if Trump unveils his plan. The Trump initiative will turn Israel’s “temporary occupation (of Palestinian territory) into a permanent occupation”, Erekat said. The Israeli-Palestinian Interim Agreement, signed in Washington in 1995, sought to put into practice the first Oslo peace deal agreed two years earlier. Sometimes called Oslo II, the interim agreement set out the scope of Palestinian autonomy in the West Bank and Gaza. The interim pact was only supposed to last five years while a permanent agreement was finalised but it has tacitly been rolled over for more than two decades. Erekat’s comment came as Israeli Prime Minister Benjamin Netanyahu was headed to Washington, where Trump was expected to release the plan before Tuesday. The Palestinian leadership was not invited and has already rejected Trump’s initiative amid tense relations with the US president over his recognition of Jerusalem as Israel’s undivided capital.
