Hamas control (2007–present) -
Hamas take-over of the Strip
In June 2007, the Palestinian Civil War between Hamas (Islamic Resistance Movement) and Fatah (Palestine Liberation Movement) intensified. Hamas routed Fatah after winning the democratic election, and by the 14th of June, controlled the Gaza Strip. Palestinian President Mahmoud Abbas responded by declaring a state of emergency, dissolving the unity government and forming a new government without Hamas participation. PNA security forces in the West Bank arrested a number of Hamas members.
Abbas's government received widespread international support. In late June 2008 Egypt, Jordan, and Saudi Arabia said that the West Bank-based Cabinet formed by Abbas was the sole legitimate Palestinian government, and Egypt moved its embassy from Gaza to the West Bank.[46] The Hamas government in the Gaza Strip faces international, diplomatic, and economic isolation.However, both Saudi Arabia and Egypt supported reconciliation and the forming of a new unity government, and pressed Abbas to start serious talks with Hamas. Abbas had always conditioned this on Hamas returning control of the Gaza Strip to the Palestinian Authority. Hamas has been invited to and has visited a number of countries, including Russia, and in the EU countries, opposition parties and politicians called for a dialogue with Hamas and an end to the economic sanctions.
After the takeover, Israel and Egypt closed its border crossings with Gaza. Palestinian sources reported that European Union monitors fled the Rafah Border Crossing, on the Gaza-Israel border for fear of being kidnapped or harmed.[47] Arab foreign ministers and Palestinian officials presented a united front against control of the border by Hamas.[48]
Meanwhile, Israeli and Egyptian security reports said that Hamas continued smuggling in large quantities of explosives and arms from Egypt through tunnels. Egyptian security forces uncovered 60 tunnels in 2007.[49]
