At least four people have been killed after a roadside bomb targeting an Afghan cabinet minister exploded in the western city of Herat, officials have said.
Mohammad Ismail Khan, the energy and water minister and a prominent anti-Taliban commander, however, escaped unharmed, a police source in Kabul, the Afghan capital, said on Sunday.
"He [Khan] was on his way to Kabul and is fine, but civilians have been killed," the source said.
Abdul Raouf Ahmadi, a local police spokesman, said: "Four people were killed, including a woman and a child. And 17 other people were wounded."
The local governor's office confirmed the toll.
"The target was Ismail Khan," Zabihullah Mujahid, a Taliban spokesman who claimed responsibility for the attack, told the Reuters news agency by telephone from an undisclosed location.
Khan, a former governor of Herat, a province bordering Iran, is a senior member of the Northern Alliance whose forces helped US forces in toppling the Taliban in 2001.
The attack wounded the minister's bodyguards, who are being treated in hospital for minor injuries, said Naqibullah Arwin, a spokesman for the local governor's office.
Witnesses told an AFP correspondent at the scene that the blast was set off by a suicide car bomber.
Afghanistan has been reeling from renewed Taliban attacks, which have stalled a Western-backed reconstruction drive.
Thousands of people have been killed and Nato and the US - with more than 100,000 troops in Afghanistan - remain bogged down in a nearly eight-year conflict.
The violence is at its deadliest level in the eight years since the 2001 US-led invasion ousted the Taliban regime in Kabul.
