Mom of missing B.C. kids previously worried dad wouldn't return them

COMOX VALLEY, B.C. — The mother of four Vancouver Island children allegedly abducted by their father overseas says she's living a nightmare.

Alison Azer's four kids, who are three, seven, nine and 11, were legally allowed to travel to France and Germany earlier this month, but they did not return as scheduled on Aug. 21.

A Canada-wide warrant for Saren Azer, who is also known as Salahaddin Mahumudi-Azer, was issued Monday for abduction in contravention of a custody order.

Saren Azer is a well-known Kurdish-Canadian doctor in the Comox Valley.

Alison Azer says she's been concerned for a long time that he would take their children and believes they may be in northern Iraq.

She says she has faith in the RCMP and international police who are looking for the children.
