The outgoing deputy force commander of the United Nations Interim Force in Lebanon (UNIFIL) was injured after a convoy taking peacekeepers to Beirut airport was "violently attacked," UNIFIL has said.
The mission demanded a full and immediate investigation by Lebanese authorities and for all perpetrators to be brought to justice, it added in a statement.
UNIFIL said the commander was returning home after ending his mission at the time of the attack.
In its statement, UNIFIL added that attacks on peacekeepers are "flagrant violations of international law and may amount to war crimes".
"We are shocked by this outrageous attack on peacekeepers who have been serving to restore security and stability to south Lebanon during a difficult time.
"We demand a full and immediate investigation by Lebanese authorities and for all perpetrators to be brought to justice.
"Peacekeepers continue to work to restore security and stability in south Lebanon in accordance with our mandate under Security Council resolution 1701."
The Irish Defence Forces confirmed that all Irish personnel deployed to Lebanon are well and accounted for following the attack.
In a statement, it said all necessary force protection measures continue to be observed.
