    GAZA, Nov. 26 (Xinhua) -- The Hamas-led Palestinian government on Sunday condemned the rocket attacks at southern Israeli towns, which breached a ceasefire with Israel and said it would look into the attacks.

    Voicing the government's discontent, spokesman Ghazi Hamad from the Hamas movement told reporters "an investigation would be open into this morning's rocket attacks."

    Hamad stressed that all factions and militant groups had accepted the agreement of ceasefire reached last night.

    "Since Israel has stopped aggression against our people, then we have to observe the granted ceasefire," Hamad added.

    Meanwhile, Palestinian President Mahmoud Abbas on Sunday ordered security chiefs to enforce the ceasefire deal with Israel after the rocket attacks.

    The launch of homemade rockets from Gaza at Israel came hours after Abbas and Israeli Prime Minister Ehud Olmert agreed on a mutual cessation of fire. The ceasefire took effect at 06:00 a.m. on Sunday.

    In return, Israel had promised to withdrew its forces from northern Gaza, according to the army.

    Saraya al-Quds, the armed wing of Islamic Jihad, and al-Qassam Brigades, the armed wing of Hamas, claimed responsibility for firing five homemade rockets at the southern Israeli town of Sderot.

    The spokesman of the Saraya al-Quds said they fired the rockets" because Israel violated the deal by arresting people in West Bankand delaying its withdrawal from Gaza for two hours."

    In the wake of the attacks, Israeli Defense Minister Amir Peretz threatened to call off the pullback and resume military operations if home-made rockets continued to fall in Sderot city.

    However, Israeli Prime Minister Ehud Olmert on Sunday said that Israel would display "patience and restraint" in the face of Palestinian breaching of the cease-fire.

    A special committee representing the government would hold another meeting later in the day with leaders of factions to discuss the violation of the deal, said Hamad.
