Unifil said such incidents were the first since Israel and Lebanese ordnance group Hezbollah agreed to a ceasefire last November.
The mission said direct fires from the Israeli military hit the periphery of the United Nations temporary forces in peacekeeping positions in Unifil, Lebanon.
The incident on Tuesday was the first time since Israel and Lebanese armed Hezbollah agreed to a ceasefire last November, Unifil added in a statement Wednesday.
Unifil said it was hit at one of its bases in the village of Kfarchouba in southern Lebanon. The Israeli army did not immediately comment.
"In recent days, Unifil has also observed other aggression by (the Israeli military) against peacekeepers who maintain and maintain operational activities," it said in an article on X.
Unifil is concerned about the aggressive posture of the IDF, involving Unifil personnel and assets near the Blue Line, including yesterday's incident, in which direct fires hit the surroundings of Unifil locations south of the village of Kfar Shouba.

It added that Tuesday's incident occurred near the blue line, an unestablished dividing line that separates Lebanon from Israel and the Israeli-occupied Golan Heights.
Any unauthorized blue line crossing the land or the air on either side constitutes a violation of Security Commission resolution 1701.
Unifil cites other alleged incidents that blame Israeli troops, including being attacked by lasers while patrolling Lebanese troops on Tuesday.
It added: “Unifil protests against all this and we continue to remind all actors of responsibility to ensure the safety and security of the United Nations personnel and property and to always respect the inviolability of the United Nations assets and the front.”
The Israeli military said Wednesday separately that it killed a Hezbollah fighter jet during a strike in southern Lebanon.
A military service.
A ceasefire ended a conflict in November, where Israel attacked Lebanon by air and invaded the country, destroying vast areas of southern Lebanon. Hassan Nasrallah, long-time leader of Hezbollah, was killed in an Israeli attack in September.
The ceasefire clause requires Hezbollah and any other armed groups to be armed in the area near the border south of the Litani River, which flows into the Mediterranean Sea about 20 kilometers (12 miles) north of the Israeli border.
They demanded that Israel withdraw troops from the southern and Lebanese forces to be deployed to the border areas.
Although the armistice officially ended the hostilities, sporadic cross-border attacks continued. Israel regularly broke the armistice and carried out air strikes in southern Lebanon and also attacked communities in southern Beirut suburbs, with Hezbollah retaining strong support.
Israel still occupies five strategic peaks along the border. Although rockets were fired from Lebanese territory to Israel on two different occasions, Hezbollah denied participation.
Hezbollah leader Naim Qassem insisted that the group no longer preserves weapons in border areas as per the armistice.
