Palestinian President Mahmoud Abbas has announced that his administration considers all agreements signed with Israel and the United States null and void, after Israel declared it would annex parts of the occupied West Bank, according to local media reports.  Palestinian news agency Wafa reported that Abbas made the announcement during an emergency meeting held in Ramallah to discuss the Israeli plans. Abbas threatened to withdraw from agreements back in February, after US President Donald Trump unveiled his Middle East plan, which included the possibility of annexation.  Al Jazeera correspondent Nida Ibrahim said the implications of the move remained unclear. During his address, which was broadcast on Palestinian television, Abbas also said he was still ready to negotiate with Israel and remains committed to ending the conflict on the basis of a two-state solution.
