Troops battling a Taliban insurgency in Afghanistan faced a "very hard summer", British Prime Minister Gordon Brown said on Friday after the death of nine British soldiers in as many days. "This is a very hard summer, it's not over but it's vital that the international community sees through its commitment," said Brown, who is attending a G8 summit in central Italy. "There's a recognition that this is a task that the world has got to accept together," he added. His comments came after officials said Friday that another two British soldiers had been killed in southern Afghanistan, taking the death toll to nine in as many days. British deaths have increased sharply since British forces launched a major airborne assault last month against a Taliban stronghold near Gereshk, in Helmand province. The situation has declined ahead of Afghan elections in August.
