An Islamic Hamas movement negotiator on Monday accused Israel and the United States for trying to block reaching a reconciliation agreement with its rival Fatah movement of Palestinian President Mahmoud Abbas.

Izzat al-Resheq, a Damascus-based Hamas leader, told local news websites that there are several reasons hindering the parties to reach an agreement, including the attempts of Israel and the United States to block reaching a deal.

The United States and Israel conditioned that dealing with any new Palestinian government headed by Hamas or includes figures of the Islamic movement has to recognize Israel and condemns violence.

Al-Resheq complained that the inter-Palestinian dialogue, mainly between Hamas and its rival Fatah, "has taken a long time and it goes so slow with procrastination," adding "Hamas is not interested in keeping cooking stones with no benefits."

On Saturday Fatah and Hamas leaders began a fifth round of dialogue in Cairo, aiming at ending a two-year political and geographical rift between Hamas-ruled Gaza Strip and Fatah-dominated West Bank.

Nabil Shaath, a senior Fatah leader revealed earlier that it has agreed with Egypt to activate different dialogue committees to overcome all differences before getting back to Cairo in July, where a deal will be signed on July 7.

Al-Resheq asserted that there are complications and differences between the two sides related to forming the government, security, the system of the upcoming elections and reforming the Palestine Liberation Organization (PLO).

"In order to reach any agreement, the two sides should present and offer mutual steps. I believe that Hamas has been all the time more flexible, but concessions has to be made by both sides," he said.

On Monday, Fatah and Hamas leaders will have their last day dialogue in Cairo to finalize an agreement on forming a joint security forces for Gaza Strip. They will get back to Cairo in early July.
