On Monday, officials reported that a suicide bomber killed at least 14 people and wounded eight in an attack on a minibus carrying security contractors in the Afghan capital of Kabul. The Taliban claimed responsibility for the attack in a statement from the Islamist group's main spokesman, Zabihullah Mujahid, on Twitter.
The attack was the latest in a recent surge of violence that highlights the challenges faced by the Afghan government in Kabul and its Western backers, as Washington slowly draws down its remaining troops, despite a persistent insurgency.
