    JERUSALEM, Jan. 14 (Xinhuanet) -- Israeli Prime Minister Ariel Sharon on Friday ordered all government officials to cut contact with the Palestinian National Authority (PNA) until it curbs violence, one day after militants killed six Israelis.

    "Israel informed international leaders today that there will be no meetings with (newly-elected Palestinian leader Mahmoud) Abbas until he makes a real effort to stop the terror," Sharon's spokesman Assaf Shariv announced.

    Three Palestinian militants on Thursday night infiltrated into the Israeli side of the Karni border crossing at the entrance to northeastern Gaza Strip and opened fire.

    At least six Israeli civilian workers were killed by the gunmen while the assailants died in a gunbattle with Israeli security guards.

    Abbas, due to be sworn in as new PNA chairman on Saturday, condemned the attack on Friday.

    Hopes have been high that following the election of Abbas to replace Yasser Arafat, Israel and the Palestinians would be able to return to the negotiation table after more than four years of conflict.

    The international community has unanimously denounced the attackand called on both sides to keep restraint.

    UN Secretary General Kofi Annan on Friday said he hoped the Gaza attack would not undermine hopes for a revival of the Middle East peace process.  Enditem
