United States Central Command conducted a strike in Syria, resulting in the death of Usamah al-Muhajir, an ISIS leader, on Friday.

The strike, which occurred in eastern Syria, was carried out by MQ-9 drones that had been harassed by Russian aircraft shortly beforehand.

The Syrian Civil Defense, a humanitarian response group often referred to as the “White Helmets,” said they responded to the scene where a person who was riding on a motorcycle on the Al-Bab-Bazaa road in the eastern part of Aleppo was killed by a drone. The group also said a civilian passing through the area sustained minor injuries.
