This comes as the International Red Cross is warning that violence is intensifying throughout Afghanistan. The Red Cross blamed the increased fighting on Taliban militants as well as U.S.-led troops. One official said: “Civilians suffer horribly from mounting threats to their security, such as increasing numbers of roadside bombs and suicide attacks, and regular aerial bombing raids.” The Red Cross said it has become increasingly challenging to carry out humanitarian work outside major cities. Meanwhile, Afghan police have arrested 11 men suspected of being involved in an attempt to kill Afghan President Hamid Karzai. On Sunday, rockets were fired at a school in the Ghazni province where Karzai was visiting.
