"PLO rejects and condemns the US finance department's decision to add Islamic Hamas movement Chief Ismael Haneyya to the terrorist list," Erekat said in a press statement.

He urged an end to internal divisions and the achievement of national unity in order to protect the national project to fight back the "schemes that aim at liquidating this national project."

Oraikat called for ending the internal split, and for achieving the Palestinian national unity in order to save the national project to fight back the "schemes that aim at liquidating this national project."

The US State Department added on Wednesday Hamas leader Ismail Haniyeh to its terrorist list.
