US serviceman killed in Iraq as Isis breaches Peshmerga lines
A US serviceman has been killed near the northern Iraqi city of Irbil, US Defence Secretary Ash Carter has said.
Mr Carter told reporters that the death was the result of enemy fire, but provided no further details.
The US-led coalition against so-called Isis said the American had been advising Kurdish Peshmerga troops.
He was killed about 5km (3 miles) behind the Peshmerga's frontline with Isis after militants penetrated it using a convoy of truck bombs, it added.
Earlier, there were reports that Isis militants had attacked on multiple fronts in northern Iraq overnight.
An Iraqi military source told that special forces had foiled an attack by five suicide bombers in the village of Khirbirdan, south of the Isis-held city of Mosul.
They also launched a counter-attack with Peshmerga fighters and Christian militiamen to recapture the predominantly Christian town of Tal Asqof, north of Mosul, after it was overrun by militants following a series of suicide car bombings.
A Peshmerga source said an attack on Wardak, east of Mosul, was also repelled.
