The Lebanese armed group Hezbollah said it launched a drone attack early Monday on northern Israel that the said wounded two Israeli troops and set off a fire.
The violence came as fears of an all-out regional war mount following the killings last week of a senior Hezbollah commander in Lebanon and Hamas' top political leader in Iran.
The Iranian-backed Hezbollah said in a statement it targeted a military base in northern Israel in response to "attacks and assassinations" carried out by Israel in several villages in south Lebanon.
The attack did not appear to be part of a more intense retaliation expected in response to the killing of Hezbollah commander Fouad Shukur in Beirut last week.
The Israeli military said fire services were working to put out a fire that was ignited as a result of the attack in Ayelet HaShahar in the upper Galilee.
Israel and Hezbollah have exchanged near-daily strikes for the past 10 months against the backdrop of the war in Gaza, but they have previously kept the conflict at a low level that had not escalated into full-on war.
Last week's assassinations of Hamas political leader Ismail Haniyeh in Iran's capital, Tehran, and Hezbollah commander Shukur in Beirut raised tensions in the region. Israel has been bracing for a retaliation from Iran and its allied militias.
