RAMALLAH, April 24 (Xinhua) -- Palestinian President Mahmoud Abbas sacked Yasser Abed Rabbo, media supervisor of the Palestinian National Authority (PNA) due to their disagreements, an Palestinian source said on Tuesday.

The source, speaking on condition of anonymity, told Xinhua that sacking Abed Rabbo as a media supervisor "doesn't mean that he was sacked as the Secretary General of the Palestine Liberation Organization executive committee."

The source added that President Abbas approved the decision of sacking Abed Rabbo and appointing him as an advisor to the Palestinian Radio and Television Corporation.

Differences between the president and Abed Rabbo emerged after the latter declined to join an official Palestinian delegation to hand Israeli Prime Minister Benjamin Netanyahu an official political letter last week.

The decision was also a response to repeated calls from leaders of Abbas' Fatah Party to sack Abed Rabbo for excluding the movement from the official mass media.

Members of the Fatah revolutionary council had earlier addressed a letter to Abbas, urging him to fire Abed Rabbo as the official supervisor of the Palestinian official media.

Abed Rabbo, replacing Nemer Hammad, became the supervisor of the official Palestinian media which includes radio, television and Wafa News Agency, in 2009.
