The dead included a child and four men, the nurse at the hospital in Azaz and the activist told Reuters.
According to Reuters, the source of the rocket attack, which took place in an area near the Turkish border is not confirmed.
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.
Turkey said its warplanes destroyed 89 targets in Syria and Iraq on Sunday, with 184 militants killed in operations targeting the YPG and PKK on Sunday and Monday.
Ankara said its weekend operation was retaliation for a bomb attack in Istanbul last week that killed six people, and which authorities blamed on the militants. Nobody has claimed responsibility and the PKK and SDF have denied involvement.
