The Taliban claimed responsibility and said the American commander was the intended target.

PESHAWAR, Pakistan — The top U.S. and NATO commander in Afghanistan, Gen. Scott Miller, escaped injury during a Taliban-claimed gun attack Thursday, but three Americans were wounded.

The police chief of the southern province of Kandahar, Gen. Abdul Raziq, was killed, reportedly along with the area’s governor and intelligence chief.

A senior official said Raziq was shot in the back by one of the Kandahar governor’s own elite guards following a high-level security meeting at the governor’s compound.

Col. Knut Peters, a Resolute Support spokesman, said the shooter was reportedly dead.

“There was a situation at the Kandahar palace today,” he said. “Initial reports indicate this was an Afghan-on-Afghan incident.”

Peters added: “Gen. Miller is uninjured. We are being told the area is secure. Initial reports also say the attacker is dead. We don’t have any more details at this time.”

While Kandahar Governor Zalmai Wesa was initially reported to have been killed in the attack, later officials clarified he was wounded and undergoing an operation. Afghan lawmaker Khalid Pashton said the regional intelligence chief, Momin Khan, was also killed.

Taliban spokesman Qari Yousaf Ahmadi claimed responsibility for attack, telling NBC News that Gen. Miller had been one of the intended targets.

“Actually we planned this attack to kill [the] U.S. military commander and his team members,” he said.

Taliban also released a Pashto-language statement claiming responsibility.

Raziq, one of the country’s top police chiefs, had survived 29 previous attempts to kill him.

Said Jan Khakrezwal, the head of the Kandahar provincial council, said the governor, Raziq and and other officials were escorting the U.S. visitors to their plane when the gunfire began.

Mushtaq Yusufzai reported from Peshawar, Pakistan; Hans Nichols from Washington, D.C.; Ahmed Mengli from Kabul, Afghanistan; and Alastair Jamieson fom London.
