The ISIS-planted landmines killed at least 10 displaced people killed were Deir Ezzor province into the southern countryside of Hasaka, local activists said on Wednesday.
Activist Mohamed al-Khedher said 30 more people were wounded in the landmines explosion.
Meanwhile, 25 families have succeeded to cross ISIS territory to Hasaka on Wednesday, according to al-Khedher.
Hundreds of families keep pouring to Hasaka as regime forces and Kurdish-led forces tighten the noose on ISIS in Deir Ezzor.
The Deir Ezzor military council, a part of the US-backed Syrian Democratic Forces, said an offensive to capture the eastern province of Deir Ezzor from Islamic State would start soon.
On Monday, powerful Kurdish PYD militia transferred hundreds of displaced people who fled from Deir Ezzor to al-Mabrouka refugee camp north of Hasaka city.
Abdul Malek al-Ali, Hasaka-based activist, said the PYD militants prevented the the escapers of ISIS battles from entering Qana camp west of Hasaka, saying the camp is overcrowded amid lack of aid and basic needs.
Asayesh, the police force of the autonomous Kurdish cantons, have transferred the displaced to Mabrouka camp in Ras al-Ayn, forcing the displaced to pay transport cost, $80 for each one, according to al-Ali.
