Prince Turki’s statement came soon after the UK Foreign and Commonwealth Office (FCO) issued a written warning advising British nationals against ‘all but essential travel to Saudi Arabia’. A statement from US authorities in the kingdom echoed that of the UK. ‘It is the embassy’s assessment that terrorist groups may place special operational significance in the upcoming month of Ramadan and American citizens are therefore urged to be particularly vigilant during this time.’ Media reports indicated that a large-scale attack similar to that of the suicide bomb attacks on three expatriate housing compounds in Riyadh on 12 May, which killed at least 34 people, was in its final stages of planning.
