An updated analysis of casualty data for British forces in Afghanistan has now been posted. Total UK casualties for the first quarter of 2011 stand at 525, including 15 fatalities, and are at similar levels to those seen during Jan-March in 2009/10. Over the last 3 years the lowest casualties have been reported during April, rising afterwards to peak during July and August in the summer fighting season. However, media reports of Taliban attacks in Kandahar during the last few days, following on from a successful escape attempt in which nearly 500 prisoners broke out of Sarpoza prison, suggest that intensification of the insurgency may be happening earlier in 2011 [BBC, Guardian].
