The Palestinian mainstream Fatah movement said on Thursday it will partake in a Hamas ceremony to mark the 25th anniversary of the Islamic movement\'s founding due here on Saturday. Fatah\'s commissioner in Gaza Yehia Rebbah said: \"We have received an official invitation from Hamas to attend the 25th anniversary of its founding. We have told them that we will be attending the event.\" He said a large Fatah delegation will be participating in the festival in Gaza. The good gesture by Fatah will favorably reflect on ongoing efforts to achieve inter-Palestinian reconciliation. Hamas political leader in Damascus Khalid Meshal is expected to attend the Palestinian resistance group\'s festival for the first time
