Anti-Western militants have adopted new tactics in Saudi Arabia, hunting down and killing individual westerners in line with published plans designed to drive out 'infidels'.
The murder in broad daylight yesterday of 44-year-old American
Robert Jacob was the latest in a series of death squad killings which security forces appear powerless to stop.
The man was pursued from a nearby clinic by two or three gunmen, who pumped him full of bullets inside his home before fleeing the scene.
He suffered nine bullet wounds to the head.
Suspected al-Qaeda gunmen shot dead an Irish cameraman and
gravely wounded a BBC correspondent on Sunday evening.
Newspapers reported that one attacker also ran after the wounded correspondent firing off more bullets and leaving him for dead.
A statement in the name of the al-Qaeda chief in Saudi Arabia
had surfaced on 27 May, urging his followers to wage an urban guerrilla war of assassinations, kidnappings and bombings.
