At least 34 were killed and 15 others wounded when a roadside bomb tore through a bus in western Afghanistan.
The bus was traveling on a main highway between the western city of Herat and the southern city of Kandahar.
All victims were civilians, mostly women and children, according to a spokesman for Farah’s governor, confirmed the toll but warned it may rise higher.
There was no immediate confirmation from the Taliban that it was behind the attack.
It came one day after the United Nations said civilians are being killed and wounded at a “shocking” level in Afghanistan’s war, despite a push to end the nearly 18-year-old conflict.
