Angry Afghan president vows security shake-up after Taliban attacks surge

KABUL (Reuters) - Afghanistan's new President Ashraf Ghani vowed to shake up security in the capital Kabul in an angry speech on Sunday and denounced a recent surge in Taliban attacks on civilian and military targets as "un-Islamic". In recent weeks, Afghanistan has seen waves of suicide bombings and commando-style assaults by the Islamist insurgents, who are seeking to make territorial gains and to spread uncertainty as most foreign troops withdraw this month.
