“It is a blatant interference in the internal Palestinian affairs and aims at putting a stick into the wheel of reconciliation.

The International Quartet, which comprises the U.S., UN, the European Union and Russia, had asked Hamas in 2006 to recognize Israel, condemn violence and recognize the peace treaties signed with Israel.

Hamas, which won in the Palestinian parliamentary elections held in 2006, rejected the Quartet’s requirements. Israel imposed a tight blockade on the Gaza Strip and the quartet imposed an embargo on Hamas movement.

“Hamas movement wouldn’t pay any attention to the attempts of sabotaging this track (internal Palestinian reconciliation and end of division) or obstructing it,” said Hamas statement.

On Oct. 12, leaders of Hamas and Palestinian President Mahmoud Abbas Fatah Party signed in Cairo on an Egyptian-brokered reconciliation agreement, where Hamas agreed to hand over the ruling of the Gaza Strip to Abbas consensus government.

Bassim Na’eem, a senior Hamas leader in Gaza, had earlier said that Greenblatt’s words are “a barefaced interference into Palestinian affairs.
