There were a lot of wounded and dead from the army. We just managed to take the wounded victims to hospital by motorbikes and vehicles, which were passing by.”<br /><br />The attacks come a day after Afghan officials signed a deal allowing US troops to stay longer than the previously agreed end of 2014.<br /><br />Former president Hamid Karzai, had refused to sign the agreement, but it was authorised by the new president Ashraf Ghani.
