Heathrow terror puzzle
BA223 cancelled for second day running
· Tension between US and British authorities
· UN resolution may be at heart of alert
Precisely why BA223 to Washington is being targeted is a mystery. The persistent warnings suggest that some conversation between al-Qaida supporters has been overheard, or a message intercepted. One theory in aviation circles was that the threat to flight BA223 might relate to UN general assembly resolution 223 passed in 1997, which attacked the Israeli treatment of Palestinians on the occupied territories. The resolution, which is among several UN declarations regularly cited by Arab states, condemned Jewish settlements on the West Bank and the Gaza strip as "illegal" and "a major obstacle to peace".
