Taliban leader Mullah Akhtar Mansour killed, Afghans confirm
Afghanistan's spy agency has confirmed that Taliban leader Mullah Akhtar Mansour has been killed, after the US targeted him in a drone strike.
The drone targeted his vehicle in a remote area of south-west Pakistan, near the Afghan border, on Saturday.
US Secretary of State John Kerry said Mansour had posed "a continuing, imminent threat to US personnel".
Mansour assumed the leadership in July 2015, replacing Taliban founder and spiritual head Mullah Mohammad Omar.
The Afghan National Security Directorate (NDS) said on Sunday that Mansour had been killed in the Dalbandi area of Balochistan province - the first official confirmation of the killing of the Taliban leader.
Afghan Chief Executive Abdullah Abdullah and defence ministry spokesman Daulat Waziri also said that Mansour had been killed.
Pakistan's government said on Sunday the drone strike was a violation of its sovereignty.
The passenger thought to be Mansour had a passport under the name Wali Muhammad and was returning from Iran, it said. He had yet to be formally identified, Pakistan said.
Who is Mullah Mansour?
- Long seen as acting head of the Taliban, and close to its founder Mullah Omar
- Born in the 1960s, in Kandahar province, where he later served as shadow governor after the Taliban's fall
- Was civil aviation minister during the Taliban's rule in Afghanistan
- Had an active role in drug trafficking, according to the UN
- Has clashed with Abdul Qayum Zakir, a senior military commander, amid a power struggle and differences over negotiations with the Afghan government
- A man claiming to be Mansour met former Afghan President Hamid Karzai for peace talks in 2010 - but it later emerged he was an imposter
The Pentagon announced on Saturday that an operation had taken place near the town of Ahmad Wal at around 15:00 (10:00 GMT) and had been authorised by President Barack Obama.
It said the strike had "probably" killed Mansour and an armed male combatant travelling with him.
There have been conflicting reports from the Taliban.
Senior commander Mullah Abdul Rauf told Associated Press that Mansour had been killed, but that the strike happened late on Friday.
Other reports denied his death. One unnamed Taliban commander told Reuters: "We heard about these baseless reports, but this not first time. Just wanted to share with you my own information that Mullah Mansour has not been killed."
False rumours have often surrounded Taliban leaders.

The death of Mullah Mansour would be a big blow for the Taliban.
He was gradually tightening his grip on the movement by bringing into his fold other leading Taliban members, including a son and a brother of his predecessor Mullah Mohammed Omar, and by launching large scale attacks on Afghan security forces.
Under his leadership, the Taliban managed to capture an important city last year for the first time in 15 years.
Mansour also managed to silence the splinter Taliban group under Mullah Muhammad Rasool, which challenged his leadership, and is credited by his followers for containing so-called Islamic State in Taliban areas.
A vacuum created by his death would once again trigger a leadership struggle.
Mr Kerry, on a visit to Myanmar, said: "This action sends a clear message to the world that we will continue to stand with our Afghan partners as they work to build a more stable, united, secure and prosperous Afghanistan.
"Peace is what we want. Mansour was a threat to that effort."
A spokesman for Afghan President Ashraf Ghani said: "Our hope in the wake of the strike is for the Afghan-led peace process to bring lasting peace and stability."
Mr Abdullah said Mansour had been "the main figure preventing the Taliban joining the peace process".
