Sterling fell to its lowest in weeks against the dollar and the euro on Tuesday, Reuters reported. British gilt yields fell to 2.62 percent from Friday\'s high of 2.76 percent, also buoyed by safe-haven flows due to escalating tensions over Syria. Sterling was down 0.4 percent at $1.5509, close to the day\'s trough of $1.5506 which was its lowest since mid-August and dipping below initial support at $1.5514, the pound\'s 200-day moving average. The euro was up 0.1 percent at 85.93 pence, close to the intra-day peak of 86.17 pence which was its highest since August 9. Chartists cited initial resistance at the April 17 high of 86.37 pence.
