Muhsin al-Fadhl, 33, was identified as the leader of the Al Qaeda-affiliated Khorasan Group - a radical terror collective specializing in intercepting Western jihadists on their arrival in Syria, and training them to carry out deadly bomb attacks on targets in their home nations.As well as an American and Arab coalition hitting targets relating to ISIS militants in Syria yesterday, the U.S. air force also independently struck Khorasan as intelligence suggested the group were nearing ‘the execution phase’ of a terror atrocity against a Western target that could have rivalled 9/11.Details of the alleged death of al-Fadhl emerged this afternoon from a U.S. military official speaking on condition of anonymity.Despite his relatively young age, the Kuwait-born militant was an Al Qaeda veteran; joining the terror group as a teenager and becoming so close to its leadership that he was among a select few with prior knowledge of the 9/11 attacks in America, despite having only just turned 20 at the time.News of Muhsin al-Fadhl's alleged death comes as a fresh wave of airstrikes hit ISIS-held territory close to Syria's border with Turkey overnight.The U.S. is confident that a barrage of close to 40 Tomahawk missiles aimed at Khorasan training camps in the Aleppo countryside killed the group's leader Muhsin al-Fadhi yesterday.'We believe he is dead,' a U.S. military official told Reuters, speaking on condition of anonymity.News of the militant's supposed death comes as a second round of airstrikes hit Aleppo province last night, according to an organisation tracking violence in Syria.Rami Abdulrahman, who runs the Syrian Observatory for Human Rights, said the warplanes carried out raids near the city of Kobani - also known as Ayn al-Arab - in Syria's western Aleppo province, with the aircraft coming from the direction of Turkey. Mr Abdulrahman added that the planes were not Syrian.Last week ISIS launched an offensive against the town, forcing more than 130,000 Syrian Kurds to flee.Although responsibility for these attacks has yet been claimed by any government - Turkey itself strenuously denies that either its airspace or strategic military bases were used to carry out the airstrikes in the early hours of this morning.While those strikes were taking place, American forces carried out a total of two airstrikes along Syria's border with Iraq and four other airstrikes inside Iraq itself, according to an anonymous official speaking with ABC News.No further details of this second wave of American attacks on ISIS have yet been revealed.The aforementioned Syrian Observatory for Human Rights said some 50 Al Qaeda militants - the majority of which are presumed to have been linked to Khorasan - were killed in the independent American air strikes, in addition to 70 ISIS jihadists killed in the 14 U.S./Arab coalition attacks.The Pentagon accused Khorasan of planning 'major attacks' against the West, saying it had eliminated the group's militants who were in the 'final stages' of plots to wreak havoc against Europe or the United States.Officials were so concerned about the group that new restrictions for passengers on US-bound flights were imposed in July to prevent a possible attack, Attorney General Eric Holder told Yahoo News.(dailymail.co.uk)Bakudaily.Az
