 Following the Egyptian Revolution of 2011 and the deposal of Egyptian president Morsi in July 2013, tensions between Fatah and Hamas reached a new high.According to Barakat al-Farra, the PLO ambassador in Cairo, the Egyptian US-backed el-Sisi regime, which annually receives some $1.5 billion military aid from the US, will keep the Rafah border crossing closed, until forces loyal to Palestinian Authority President Mahmoud Abbas have regained control.A Hamas official accused the PA leadership of playing a major role in enforcing the blockade of the Gaza Strip.
