The Israeli military said on Saturday it had struck "military infrastructure" at the Syria-Lebanon border allegedly being used by Hezbollah for weapons smuggling in violation of their ceasefire agreement.

Turkey Friday demanded an end to "attacks" on the rebel enclave of Idlib in Syria, where Syrian and Russian warplanes reportedly launched airstrikes.

"We have emphasized that these attacks must come to an end," the Turkish foreign ministry said in a message on X. "The recent clashes have resulted in an undesirable escalation of tensions in the region."

The Israeli army said Friday it had struck a Hezbollah rocket launcher in southern Lebanon after detecting militant activity in the area two days after the start of a ceasefire.

"A short while ago, terrorist activity and movement of a Hezbollah portable rocket launcher were identified in southern Lebanon. The threat was thwarted in an (Israeli Air Force) strike", the army said in a statement that featured a video of the air strike on a slowly moving truck.

Iran, Britain, France and Germany were meeting in Geneva on Friday under a shroud of secrecy to discuss Tehran's nuclear program, amid surging tensions even before Donald Trump's return to the White House.

In a rare show of discretion, the countries foreign ministries were providing no details on the topics to be discussed, or even the specific time and venue for the talks or how long they were due to last.

Army chief Joseph Aoun, who is being touted as a possible candidate for the presidency, is a man with a tough mission following an Israel-Hezbollah ceasefire that relies heavily on his troops deploying in the south.

Aoun, 60, was set to retire last January after heading the army since 2017, but has had his mandate extended twice -- the last time on Thursday.

A truce between Israel and Hezbollah, brokered by the United States and France, called for an initial two-month ceasefire in which the militants are to withdraw north of the Litani River and Israeli forces are to return to their side of the border.

For many Lebanese, the pause in fighting brought relief — but also heartache. Displaced families returned home to sift through the bombed-out ruins of their shops and apartments.

France's special envoy on Friday said it was urgent for Lebanon to elect a president, after a parliamentary vote to end over two years without a head of state was announced for January.

Jean-Yves Le Drian's visit to Lebanon follows a fragile ceasefire to end the war between Israel and Hezbollah.

Jihadists and their allies cut a major highway linking the main cities of Damascus and Aleppo on Thursday after launching an offensive against government forces in Syria's northwest, a war monitor said.

"Hayat Tahrir al-Sham (HTS) and allied factions cut off the Damascus-Aleppo international M5 highway... in addition to controlling the junction between the M4 and M5 highways," said the Syrian Observatory for Human Rights.

Lebanon's health ministry said on Thursday that 3,961 people had been killed and 16,520 wounded in more than a year of hostilities between Israel and Hezbollah, including two months of all-out war.

"The total number of dead and wounded since the start of the aggression until Tuesday reached 3,961 dead and 16,520 wounded," a ministry statement said, adding that the increased numbers were also due to "dead being removed from under the rubble".

The Swiss government, which previously drafted a law explicitly banning Hamas activities and support for the Palestinian militants, decided this week against doing the same for the Lebanese armed group Hezbollah.

Parliamentary security policy committees had called for a ban on Hezbollah, but in its response published Thursday, the federal government said the conditions had not been met.
