In answer to my own question, Abu Mazen (Palestinian President Mahmoud Abbas) is back in Ramallah in time to meet U.S. Special Envoy on the Middle East, George Mitchell at 18h30, in Ramallah’s presidential headquarters, the Muqata’a, in about 25 minutes’ time.
Sa’eb Erekat is due to give a press briefing at the Muqata’a at 20h30.
Otherwise, most of the rest of Ramallah is observing a general strike against what are perceived as Israeli threats to Al-Aqsa Mosque, and restrictions on allowing Muslim worshippers to get there, in the Old City of East Jerusalem. The strike was called by Fatah’s Central Committee.
