A total of 230 Irish soldiers are arriving in Lebanon this morning, to begin a six-month tour of duty.
The deployment represents the first of two troop movements that will see a total of 440 members of the 105th Battalion taking up peacekeeping duties with the UNIFIL mission.
The second half of the Battalion flies out on November 27.
The troops will take over duty from the 104th Battalion, who've been in Lebanon since June.
The role of Irish troops in the UNIFIL mission involves monitoring the cessation of hostilities, assisting the Lebanese Armed Forces and helping to ensure humanitarian access to the civilian population.
