According to Iraqi Prime Minister Haider al-Abadi, Iraq's air force on Friday carried out its first airstrikes on Islamic State targets inside Syria. The move comes just one day after Iraqi troops seized the Mosul airport from ISIS. Meanwhile in Syria, an alleged Islamic State car bomb was detonated in the village of Sousian, which had already been recaptured from militants. The explosion killed dozens of people—including many civilians—when it was detonated at a security checkpoint controlled by Turkey-backed rebels. A leading Syrian opposition fighter in the area, Mohammed al-Tawil, said a suicide attacker blew a small pickup truck outside of a security office. At least 35 civilians are dead, Reuters reports. The attack, in the village of Sousian, may have killed up to 42 people, according to the Britian-based Syrian Observatory for Human Rights.
