Video shows aftermath of rocket attack in Syria

STORY: The dead included a child and four men, the nurse at the hospital in Azaz and the activist told Reuters.

Reuters was not immediately able to verify the source of the rocket attack, which took place in an area near the Turkish border that is under the control of Turkey-backed Islamist rebels.

The incident follows attacks by Turkish drones and warplanes on the Kurdish YPG militia in Syria in the last few days as Turkey and the YPG escalated tit-for-tat strikes that have killed civilians on both sides of the border.
