Lebanon on Sunday claimed that an Israeli warship had breached its territorial waters.
According to Lebanese TV channel LBC, the ship crossed over near a beach in Israel's Rosh Hanikra, a coastal region in the north that borders Lebanon. According to UN peacekeeping force UNIFIL, the incident lasted only several minutes before the vessel returned to Israeli waters.
The IDF has yet to comment on the incident.

The maritime border between Israel and Lebanon has been a point of dispute, with negotiations making a significant breakthrough in May with Israel's approval of Beirut's proposal on the border's demarcation.
Energy Minister Yuval Steinitz released a statement saying there had been a round of talks between Israeli and Lebanese officials in an effort to agree on a border mediated by the US, taking into account both country's interests in natural gas reservoirs in the region.
Israel and Lebanon do not have diplomatic relations but have clashed repeatedly over the unsolved maritime border dispute, right in the vicinity of regional underwater fossil fuel reserves.
