A chemical weapons expert from the Islamic State (IS) group in Iraq has been captured by US special forces and is being questioned, reports say.

The man was once a specialist in chemical and biological weapons for Saddam Hussein, the Iraqi leader overthrown by the US invasion in 2003, Iraqi and US sources told US media.

Named as Sleiman Daoud al-Afari, he was reportedly seized last month.

In a statement to the BBC, the Pentagon would not confirm his capture.

However, its spokesman confirmed US special forces had begun operations in Iraq - part of a more aggressive strategy against IS.

The man has already told interrogators how IS loaded mustard gas into shells, US sources told the New York Times

Last month, sources at the global chemical watchdog, the Organisation for the Prohibition of Chemical Weapons (OPCW), announced that sulphur mustard had been used last year in an attack on Kurdish forces in Iraq blamed on IS.

If confirmed, it would be the first known use of chemical weapons in Iraq since the fall of Saddam.

Banned weapon

Mr Afari was identified as a former employee of the Military Industrialisation Authority, which functioned under Saddam, who used poison gas against Iraq's Kurdish community in the 1980s.

Unnamed US defence sources told the New York Times Mr Afari was being held in Irbil, a Kurdish stronghold in northern Iraq.

He is being questioned about IS plans to use mustard gas, which is banned under international law, in Iraq and Syria, the paper says.

The alleged IS weapons expert reportedly gave his captors details of how the group had weaponised mustard gas into powdered form and loaded it into artillery shells.

One defence official quoted by the paper said the gas was not concentrated enough to kill anyone but that it could maim people.

Mustard gas, which is liquid at ambient temperature, is a powerful irritant and blistering agent which causes severe damage to the skin, eyes and respiratory system and internal organs.

The International Committee of the Red Cross (ICRC) visited the prisoner after it was notified of his capture by US officials, the paper adds. No details were given.

Two unnamed Iraqi intelligence sources quoted by the Associated Press news agency described Mr Afari as the head of the IS unit trying to develop chemical weapons.

IS leaders targeted

A Pentagon spokesman told the BBC on Wednesday: "I cannot confirm these reports.

"What I can tell you is, and as the [Defense] Secretary [Ashton Carter] said recently, the Expeditionary Targeting Force [ETF] has begun operations in Iraq, but we will not discuss the details of those missions when it risks compromising operational security.

"One of the goals of the ETF is to capture ISIL [IS] leaders. Any detention would be short-term and coordinated with Iraqi authorities."

US officials announced last week that a US commando force had captured an IS leader in Iraq without giving his name.
