(AINA) -- According to the Vatican ambassador in Damascus, Mario Zinari, 52 Assyrian families who were captured by ISIS and who were supposed to be freed yesterday have not been released because Kurdish forces bombed the caravan containing the families. After the bombing ISIS decided to delay their release. There is no information on whether ISIS intends to go through with their release.

It is not clear why Kurdish forces bombed the Assyrian hostages caravan.

Yesterday AsiaNews reported that 52 Assyrian families had been freed.

On February 23 ISIS attacked the Assyrian villages of Tel Goran, Tel Hurmiz, Tel Tamar, Tel Baloaa Tel Shamiran, Tel Riman, Tel Nasra, Tel Khareta, Tel Jazira, Tel Fweidat, Qaber Shamiyeh and Abu Tena.
