By Daily Mail Reporter PUBLISHED: 08:20 EST, 1 October 2012 | UPDATED: 06:12 EST, 2 October 2012 A suicide bomber driving a motorcycle packed with explosives rammed his bike into a patrol of Afghan and international forces on Monday morning in eastern Afghanistan, killing at least 14 people, including three NATO service members and their translator, officials said. The Taliban claimed responsibility for the blast, which came as relations between international forces and their Afghan partners have been pushed to the breaking point by a surge in insider attacks by Afghan allies. The attack comes as top Afghanistan official General John Allen blasted the rash of insider attacks, saying he was 'mad as hell' that terrorist forces were taking advantage of the United States' 'vulnerabilities' during the troop withdrawal and warned that the insider attack would be the 'signature' of the current stage.
