CAIRO, Jun 30 (Aswat Masriya)- Egyptian authorities will extend the opening of the Rafah border crossing between Egypt and the Gaza strip to Monday, the Palestinian embassy in Cairo said on Thursday.

The crossing was initially set to be open on Wednesday, Thursday, Saturday and Sunday, the embassy added in a statement. 

The border was last opened early June for four days.

The Rafah border crossing connects the residents of the besieged Gaza strip with Egypt and the rest of the world. It has been largely closed after a large-scale militant attack on the Qarm al-Qawadis checkpoint in October 2014 in Egypt's Sinai Peninsula , which borders Gaza. The attack left 33 Egyptian soldiers dead.

Gaza's area is around 360 square kilometers and is home to more than 1.76 million people, making the enclave among the world's most densely-populated areas. 

The Strip has been under a land, air and sea blockade enforced by Israel since 2007, after the Palestinian Islamic Resistance Movement (Hamas) won the Palestinian legislative election and took control of the strip.

Cairo-Hamas ties have been strained since the military ouster of former president Mohamed Mursi of the Muslim Brotherhood in July 2013, after mass protests against his rule. The Palestinian movement was a strong ally of Mursi's regime.

Mursi's ouster was followed by a rise in militancy, especially in Egypt's Sinai Peninsula. Egyptian authorities frequently linked the Palestinian movement to the rise of insurgency in Sinai but Hamas has repeatedly denied such accusations.
