An Israeli warship briefly entered Lebanese waters on Monday but was intercepted by an Italian ship operating as part of the UN peacekeeping force, the army said on Tuesday.
"An Israeli Saar warship entered Lebanese territorial waters at 7:30 am (0530 GMT) yesterday morning before being intercepted by the Italian navy's Bettica, which is part of UNIFIL," an army spokesman said.
The Israeli vessel travelled three miles (about five kilometres) before leaving , according to an army statement.
Israeli jets regularly violate Lebanese airspace, but it is rare for warships to enter Lebanese territorial waters.
Yasmina Bouziane, spokeswoman for the UN Interim Force in Lebanon (UNIFIL), and said an investigation was underway.
"We received a report saying that a ship coming from Israel entered the maritime area of operation without proper procedures, violating Lebanese territorial waters," she said.
"UNIFIL is investigating this issue and UNIFIL command has contacted the IDF (Israeli Defence Forces)."
The overflights have drawn criticism from Lebanese authorities and the international community as they are in violation of UN resolution 1701, which ended the 2006 war between the Hezbollah and Israel.
