An airstrike has killed a top al-Qaida commander and two other fighters in Syria, activists said Saturday, but it was not immediately clear whether it was carried out by the U.S.-led coalition or Russian warplanes. The Britain-based Syrian Observatory for Human Rights said Abdul Mohsen Abdallah Ibrahim al-Charekh, a Saudi better known as Sanafi al-Nasr,
was killed Thursday in an airstrike near the northern Syrian town of Dana, along with another Saudi and a Moroccan member of al-Qaida’s local affiliate, known as the Nusra Front. Russian warplanes have been carrying out airstrikes in Syria since Sept. 30. A U.S.-led coalition has been targeting the Nusra Front and the Islamic State group for more than a year.
