The attacks were directed at "Hezbollah targets" in the Beka'a Valley, according to an Israeli account. It is far into Lebanon from Israel's perspective, beyond the disputed border areas in the south and east of the capital Beirut.
According to Israel, the targets were some kind of tunnels where weapons are manufactured and where the Lebanese Shia militia Hezbollah is alleged to be able to smuggle weapons across the border to Syria just east.
Two people were killed and ten injured, reports Lebanon's Health Department.
There were four attacks and they were directed at border crossings near the village of Janta, reports the Lebanese newspaper L'Orient le Jour's correspondent in the Beka'a Valley. Israel has attacked there before and then claimed to stop weapons smuggling, but it was several weeks since last.
On Thursday, the Israeli military reported that a reconnaissance drone had been shot down while on its way to Israel. This was said to have been followed up by a counterattack where a vehicle belonging to Hezbollah was fired upon on the Lebanese side of the border.
The drone constituted "a breach of the agreement between Israel and Lebanon", according to the Israeli military's spokesperson Avichay Adraee. According to him, Israel will continue to follow the agreement and the ceasefire.
An agreement reached in November led to a ceasefire between Israel and the Lebanese Shia militia Hezbollah, two months after a full-scale war where Israeli forces advanced into Lebanon.
As part of the agreement, it is up to Lebanon's regular but relatively weak army to place forces in the south, where they are to maintain peace together with international UN forces.
In turn, Hezbollah is to withdraw northwards, north of the Litani River and further away from Israel.
This was to happen by January 26 at the latest, but the deadline was extended at a late stage to February 18. There had then been a brief escalation since the parties had accused each other of numerous violations and attempts to delay their withdrawals.
Even earlier agreements over the past decades have aimed to establish a buffer zone in southern Lebanon, but it has not happened in practice, largely due to Hezbollah's continued strong influence.
