The US-led coalition carried out a drone strike Wednesday in northwestern Syria targeting a senior al-Qaeda leader, the US military said. The Syrian Observatory for Human Rights, an opposition war monitor, said the strike hit a chicken farm near the town of Harem, killing one person. It said the dead man has not been identified yet. The strike was the latest of a series of similar attacks over the past years that have killed senior members of the ISIS group or al-Qaeda. The US Central Command said that shortly before noon, US forces conducted “a unilateral strike” in northwestern Syria, targeting a senior al-Qaeda leader. It added that more information would be provided "as operational details become available.” US Army Gen. Erik Kurilla, the top US commander for the Middle East said the strike on Wednesday “reaffirms CENTCOM’s steadfast commitment to the region and the enduring defeat” of ISIS and al-Qaeda. Most of those targeted over the past years had been members of Horas al-Din. The group includes hardcore al-Qaeda members who broke away from Hayat Tahrir al-Sham, the strongest al-Qaeda-linked militant group in Idlib province. In 2017, a US airstrike killed a former aide to Osama bin Laden and al-Qaeda’s second in command in Syria, Abu al-Kheir al-Masri. Idlib is the last major opposition enclave in war-torn Syria.
