Department of Foreign Affairs advising against non-essential travel to Turkey
Aer Lingus is offering customers a full refund if they are travelling to Nice in France, or Izmir in Turkey.
In a statement, the carrier says: "Due to the tragic events in Nice we are allowing guests who have flights booked to travel between Dublin and Nice on dates between the 16th and 29th July to change for free for a span of two weeks from the date of original booking or to request a full refund if preferred."
It adds: "We are also aware of the overnight security situation in Turkey and are currently accessing the situation with authorities."
It says those who have flights booked to travel between Dublin and Izmir between the 16th and 29th of July have the option to either change for free for a span of two weeks from the date of booking, or request a refund.
The Irish Travel Agents Association (ITAA) say they are monitoring the situation in Turkey in close partnership with the Department of Foreign Affairs.
"ITAA member agents are striving to keep customers informed and facilitate anyone who needs to change their travel plans," it says in a statement.
Meanwhile the Department of Foreign Affairs is advising Irish citizens to exercise "a high degree of caution" in Turkey.
"The Department of Foreign Affairs and the embassy in Ankara continue to monitor developments following the thwarted coup attempt on 15 July," it says.
"The situation in Ankara and Istanbul in particular remains tense, and there is a heightened security presence on the streets in both cities. There have been incidents of violence, and Irish citizens should be extremely vigilant and stay informed of local developments and security advice."
It also says there has been serious disruption to public transport - including international and domestic air travel.
While the department is also asking Irish people in France to "exercise a high degree of caution."
"Irish citizens in Nice should closely follow the advice of local authorities, which is currently to remain indoors, and that the area around the Promenade des Anglais is closed", it adds.
