2004 Yanbu attack
The 2004 Yanbu attack was an attack by gunmen against Westerners on May 1, 2004, in Yanbu' al Bahr, Saudi Arabia.
At least four militants used security passes to access a local petrochemical plant. Once on the grounds of the facility, they stormed the offices of the Texas-based ABB Lummus and killed seven people. Two were Americans, two were British, one was Australian and one was a Saudi National Guard member. A Canadian worker died May 15 of his wounds.
The attackers were believed linked to Al Qaeda, though Crown Prince Abdullah, de-facto ruler of Saudi Arabia, disputed these claims. Since 2003, militants have carried out attacks against the Saudi government and foreigners living there in an effort to topple the monarchy. Less than a month after these attacks, gunmen staged a similar attack in Al-Khobar, killing 22.
