LONDON — AUGUST 11: Two young boys and their father pray outside the Dar Al Uloom Qadria Jilania Mosque and Religious School in Walthamstow on August 11, 2006 in London, England. Police were today still searching premises near to the mosque following the arrests of 21 people. British Airports were yesterday thrown into chaos as Airport security was heightened to critical after a terrorist plot to blow up planes in mid-flight from the UK to the US was disrupted by police.
