Israel said eight of its soldiers were killed in combat in south Lebanon as its forces thrust into its northern neighbour in a campaign against the Hezbollah armed group.
The losses were the deadliest suffered by the Israeli military on the Lebanon front in the past year of border-area clashes between Israel and its Iranian-backed Lebanese foe.
Hezbollah said its fighters were engaging Israeli forces inside Lebanon, reporting ground clashes for the first time since Israeli forces pushed over the border. Hezbollah said it had destroyed three Israeli Merkava tanks with rockets near the border town of Maroun El Ras.
Israeli Prime Minister Benjamin Netanyahu, in a condolence video, said: “We are at the height of a difficult war against Iran’s Axis of Evil, which wants to destroy us.
“This will not happen because we will stand together and with God’s help, we will win together,” he said.
The Israeli military said regular infantry and armoured units were joining its ground operations in Lebanon.
Hezbollah said it had repelled Israeli forces near several border towns and also fired rockets at military posts inside Israel.
The paramilitary group’s media chief Mohammad Afif said those battles were only “the first round” and that Hezbollah had enough fighters, weapons and ammunition to push back Israel.
Israel’s addition of infantry and armoured troops from the 36th Division, including the Golani Brigade, the 188th Armoured Brigade and 6th Infantry Brigade, suggested that the operation might expand beyond limited commando raids.
The Israeli military has said its incursion is largely aimed at destroying tunnels and other infrastructure on the border and there were no plans for a wider operation targeting the Lebanese capital Beirut to the north or major cities in the south.
Nevertheless, it issued new evacuation orders for around two dozen towns along the southern border, instructing inhabitants to head north of the Awali River, which flows east to west some 60 km (37 miles) north of the Israeli frontier.
