A US-led coalition captured a senior member of the Islamic State group in northwest Syria on Wednesday, state media and a war monitor reported. It was not immediately clear if the man is the IS supreme leader. Abu Hafs al-Qurayshi, an Iraqi citizen and IS commander, was detained during a pre-dawn operation that included landing troops from helicopters in the town of Atmeh, near the Turkish border. Another Iraqi citizen was killed, according to the Britain-based Syrian Observatory for Human Rights.

The US military did not respond to a request for comment. The Observatory said the man captured had a French-speaking woman with him, and it was not immediately clear if she was taken by the US force or by Syrian security forces who later cordoned the area. Two years ago, IS announced that a man called Abu Hafs al-Hashemi al-Qurayshi was named as its new leader after Turkish authorities killed his predecessor.

Syrian state TV on Wednesday quoted an unnamed security official as saying the Iraqi man targeted in the operation is known as Ali, adding that his real name is Salah Noman. It said Noman was living in an apartment with his wife, son and mother. It said he was killed in the raid.
