baghdad - Iraq said Wednesday that a strike by the US-led coalition targeted top Islamic State leaders, including a man presented as the second-in-command, but the US military cast doubt on the claim.

‘Based on accurate intelligence, an air strike was carried out by the international coalition targeting the number two in the Daesh terrorist organisation Abu Alaa al-Afari,’ the ministry of defence said in a statement. Daesh is an Arabic acronym for the Islamic State jihadist organisation, which took over swathes of Iraq last year.

It was not clear from the statement whether Afari was killed in the strike, which the ministry said targeted a gathering in the Martyrs’ Mosque in Tal Afar’s Al-Ayadiya district. Reacting to reports that Afari had been killed, the US Central Command overseeing the air war against the IS group, said it had ‘no information to corroborate these claims.’

‘However, we can confirm that coalition aircraft did not strike a mosque as some of the press reporting has alleged,’ it said in a statement. The Iraqi defence statement did not say when the raid was conducted but came with a video of the alleged hit - grainy black and white aerial footage of a building being destroyed in an apparently scarcely populated area. Afari’s name emerged last month in reports claiming that IS head Abu Bakr al-Baghdadi was incapacitated in a coalition strike and handed over the helm of the organisation to Afari.

The Pentagon however had said at the time there was no reason to think Baghdadi had been wounded. The structure of the organisation’s senior leadership is secretive and IS has only released video or audio recordings of Baghdadi or the group’s official spokesman Abu Mohammed al-Adnani. The defence ministry Wednesday also said the strike targeted the top IS judge in the group’s self-proclaimed Jazira province, which includes Tal Afar, and ‘a large number’ of the organisation’s members.

Tal Afar lies near the border with Syria, almost 400 kilometres (250 miles) northwest of Baghdad, and was one of the first places IS fighters took over when they launched a surprise offensive on June 9 last year. The US State Department last month put a $7 million bounty on information leading to Afari, who is presented on the Rewards for Justice website under the name of Abd al-Rahman Mustafa al-Qaduli.

The Islamic State militant group has seized large parts of a strategically located town in Syria’s central Homs province in clashes that killed 48 soldiers and militants, a monitor said Wednesday.

The Syrian Observatory for Human Rights said the extremist group had captured areas of Al-Sukhnah and its surroundings in fighting that began overnight.
