The second-in-command of Islamic State (IS) has been killed in a US-led coalition air strike in northern Iraq, the Iraqi ministry of defence says.

Abdul Rahman Mustafa Mohammed, also known as Abu Alaa al-Afari, was at a mosque near Tal Afar that was targeted, spokesman Brig-Gen Tahsin Ibrahim said.
However, the US military later denied coalition planes had attacked a mosque.
In recent weeks, there were unconfirmed reports that Afari had taken temporary charge of IS operations.
Iraqi sources claimed IS leader Abu Bakr al-Baghdadi had been incapacitated as a result of an air strike in Iraq in March.
Gen Ibrahim told the BBC that Afari was killed alongside dozens of militants who he had been meeting at the al-Shuhada (Martyrs) mosque in the village of al-Iyadhiya, near Tal Afar, where he was reportedly a well-known preacher.
Tal Afar, in the northern province of Nineveh, was seized by IS in June 2014.
The general did not specify which country had carried out the air strike, but the US has been responsible for the vast majority since the coalition campaign began last August.
The ministry of defence separately published video purportedly showing the strike. It did not say when it took place, but one official told the Associated Press it was on Tuesday.
The Governor of Nineveh, Atheel al-Nujaifi, told the BBC in Washington that his contacts had confirmed Afari's death.
The US-led coalition said on Wednesday it had carried out a strike in the Tal Afar area against "an Isil (IS) fighting position and an Isil heavy machine gun", adding: "We can confirm that coalition aircraft did not strike a mosque."
Adding to the confusion, the Iraqi interior ministry was quoted as saying that although Afari was present at the scene of the air strike, it wasn't clear what had happened to him.
The Iraqi government has previously announced the deaths of IS leaders only for them to resurface alive.
But the BBC's Ahmed Maher in Baghdad says that if Afari's death is confirmed, it would represent another blow to IS, which has suffered a series of losses on the battlefield in recent months.
Last week, the US state department offered a reward of $7m (£4.5m) for information on a "senior IS official" called Abdul Rahman Mustafa al-Qaduli, whom Iraqi security sources identified as Afari.
Born in 1957 or 1959 in Iraq's second city of Mosul, Qaduli joined IS forces in Syria after his release from an Iraqi prison in 2012, it said. He had previously served as the leader of al-Qaeda in Iraq (AQI) - a precursor of IS - in Mosul.
The US added Qaduli to its list of specially designated global terrorists in 2014.
