Most UNIFIL confrontations were stand offs. Occasionally they flared up into exchanges of gunfire. At-Tiri has been covered in another thread. But in short it was probably the most serious confrontation in UNIFIL's history. Apart from exchanges of SA fire, UNIFIL also fired 90mm from the Panhards and destroyed at least one SLA vehicle. Dutchbatt fired TOW missiles but as warning shots only, I think. Irishbatt suffered one fatality directly-Pte Griffin died of his wounds on 16th April. A Fijian soldier was KIA also. Several SLA men died and two Irish soldiers were killed in revenge the following week. Three Irish soldiers were abducted and threatened with execution at the time also. And there were daily bombardments of Irishbatt positions by SLA artillery. They even wrote a song about it called Christian Shells :D All in all it was almost as bad as a Saturday night in Limerick.
just to stop the sla from moving into a village.
The UNIFIL zone officially extended right to the Israeli border. So the Enclave or the Israeli Controlled Area occupied part of the UN Zone. At Tiri was inside the ICA and SLA transport had to pass through the Irishbatt Checkpoint there. The confrontation was caused by the issue who had primacy- the UN or the SLA. The conflict with Haddad's men was exacerbated by Brian Lenihan who was Ireland's Minister for Foreign Affairs at the time. On a visit to the Middle East (Bahrain I think) he made a speech where he recognised the PLO as representing the Palestinian people. Since Irishbatt was engaged in preventing PLO incursions into Israel at the time this stupid statement undermined Irish neutrality in Lebanon and ultimately killed Irish troops.
