The Department of Foreign Affairs has said it is aware that Irish tourists are in Sousse, but that it has had no reports of Irish injured. It is activating its Consular Crisis Centre as a precaution.
“The Embassy in Madrid and our Honorary Consul, in conjunction with EU Embassies in Tunis, are monitoring the situation in Sousse, Tunisia, and are providing updates,” a statement from the Department read.
“We are aware of Irish citizens in Sousse but we are not aware that any Irish citizens have come to harm. Given the number of Irish holiday makers in Tunisia we have opened a dedicated consular support line as a precautionary measure.
“Anyone with concerns about this incident should call the Department on 01 418 0200.
“Irish citizens in Sousse are advised to follow the instructions of the police, tour operators, and their hotel staff.”
Tunisia has been on high alert since March when militants killed 22 people, mainly foreign tourists, in an attack on a museum in the capital Tunis.
