Lisa Smith, the former Irish soldier who became a supporter of Islamic State, may be among hundreds of women and children reported to have fled a detention camp in Syria against the backdrop of the Turkish military incursion.

Ms Smith (38) and her two-year-old child, as well as the Irish-born child of another Isis supporter, were all believed to be in the camp. Their whereabouts now are unclear.

Local media group Rojava Information Centre said 859 people had escaped from the foreigners section of the Ain Issa camp, where women and children linked to Isis were being held.

Isis had sent out calls for an uprising in the surrounding area to assist the “escape attempt”, the group said on Twitter. The Kurdish authorities also said the women and children had escaped from the camp.

Mr Bekmirzaev is believed to be a prisoner in Syria but his exact whereabouts are unknown.

Asked about developments at Ain Issa, a spokeswoman for the Department of Foreign Affairs said it would, as in all cases where Irish citizens abroad were in danger, engage with partners and provide consular advice and assistance.

“Given the particularly volatile and complex situation in the region, it would not be appropriate to comment on specific cases or any possible course of action.”

Last week, the gardaí confirmed that both Ms Smith and Mr Bekmirzaev are being investigated under the Criminal Justice (Terrorist Offences) Act 2005, which prohibits membership of domestic and foreign terrorist groups.

During her time with the Air Corps, Ms Smith worked as a flight attendant on the Government jet, and as a driver for senior officers.

Turkey has said its attack on northern Syria, which began last week, is designed to create a safe zone along the border and that its sole target is Kurdish fighters whom they say are “terrorists”.

The Kurdish-led Syrian Democratic Forces (SDF) were supported by US troops in their battle against Isis in Syria. Turkey launched its military incursion after the US president Donald Trump spoke on the phone with Mr Erdogan and subsequently announced the withdrawal of US troops from the area.
