BEIJING, June 1 (Xinhuanet) -- While a number of countries condemned the terror attacks and voiced support to Saudi anti-terror efforts, some countries expressed worries that there may bemore terror attacks to come.

    Militants took 45 to 60 hostages, most of them foreigners, and holed them up in a six-story building since Saturday after attacking oil facilities in the eastern oil city of Khobar, some 400 kilometers northeast of Riyadh, capital of Saudi Arabia.

    About 40 Saudi commandos stormed the building early Sunday, capturing one of the four assailants and freeing the hostages heldby the militants. But the three others escaped.

    An organization called itself the "al-Qaida in the Arab Peninsula" issued a statement on the Internet claiming responsibility for the attack, the second this month against the Saudi oil industry.

    The attack, which pointed at the oil policy of Saudi Arabia, sparked widespread international outcry.

    Saudi forces have been hunting for the three suspected Al-Qaidamilitants who escaped a massive security cordon after a bloody weekend hostage-taking rampage which left 22 people dead.

    China condemned the attacks on civilians and expressed resolute support to Saudi Arabia's counter-terrorism efforts, Chinese Foreign Ministry spokesman Liu Jianchao said Monday.

    US President George W. Bush on Monday called Saudi Crown Prince Abdullah bin Abdul Aziz to offer his condolences to victims in theattacks and reaffirmed his commitment to "the global war on terror."

    The Gulf Cooperation Council (GCC) denounced the attacks as a terror act and voiced its support for Saudi Arabia to fight terrorism.

    Kuwait issued a statement Sunday, condemning the "ugly criminal" act and expressing solidarity with Riyadh in confronting terrorism and protecting its people and residents.

    The United Arab Emirates voiced its support for Saudi Arabia touse force against the criminals, while Egyptian Foreign Minister Ahmed Maher condemned the attack and stressed the need to build a common front to end terrorist acts.

    In Europe, several countries condemned the brutality and others expressed worries that more terror attacks will come.

    Italian Prime Minister Silvio Berlusconi on Sunday reaffirmed Rome's commitment to fighting terrorism.

    The French Foreign Ministry said France would remain more than ever at Saudi Arabia's side in the mobilization necessary to fight terrorism.

    Swedish Foreign Minister Laila Freivalds on Sunday called for steps to further improve and increase the efficiency of international cooperation in the fight against terrorism.

    Countries such as India, South Africa, Turkey and Kuwait also joined the chorus of condemnation against Saturday's terror attacks in Saudi Arabia.

    However, other countries, including Britain and Australia, warned that terrorists were planning further attacks against foreigners in Saudi Arabia. "(Attacks) are clearly very possible,"said Britain ambassador to Saudi Arabia, Sherard Cowper-Coles.

    As analysts worry that the attacks in Saudi Arabia, the world's biggest oil producer, would effect world oil market, an official said Monday that the Organization of Petroleum Exporting Countries would produce "as much as the market can absorb" to calm concerns about oil supply and price following the weekend attacks.

    "We will supply the market, as much as the market can absorb," Qatari Energy Minister Abdullah bin Hamad al-Attiya told the press ahead a meeting of the OPEC due Thursday in the Lebanese capital of Beirut. Enditem
