A militant group linked to al-Qaida has taken credit for Wednesday’ s bombing of the national police headquarters in Saudi Arabia. Some analysts say the attack opens a new chapter in al-Qaida’s fight against the West and its allies in the Middle East. Analysts in tile region are offering explanations, and advice on what the Saudi government should do about it.
   The Saudi government expressed outrage at the bombing, and in Cairo, Arab League Secretary General Amr Moussa condemned tile attackers for, in his words, terrorizing our societies.
   Mr. Moussa said most of the victims are civilians, and he called the attack unacceptable.
   The attack, carried out by Muslims against Muslims, also drew harsh condemnation from Saudi Arabia’s highest religious authority, which said unjustly killing a Muslim is the gravest crime.
   In Egypt, the banned Islamic group known as the Muslim Brotherhood also condemned the Saudi blast as destabilizing and damaging to Islam.
   So why do such attacks continue in spite of both secular and religious criticism in the Arab world? Mohammed Salah, director of the Arabic language al-Hayat newspaper in London, says anger against U. S. policies in the region is encouraging groups like al-Qaida.
   Mr. Salah says antagonistic feelings against the West are leading the attackers to target governments they see as supporting the United States. Anger is particularly sharp over the invasion of Iraq and U. S. support for Israel.
