Blinken says 'ceasefire is holding' in Lebanon

US Secretary of State Antony Blinken said Wednesday the ceasefire in Lebanon was "holding" despite a series of incidents between Israel and Hezbollah.

"The ceasefire is holding, and we're using the mechanism that was established when any concerns have arisen about any alleged or purported violations," Blinken told journalists on the sidelines of a NATO meeting in Brussels.

Both Israel and Hezbollah face accusations of having  breached the truce that took effect last Wednesday to end a war that has killed thousands in Lebanon and sparked mass displacements on both sides.

A source from the UN's peacekeeping forces in Lebanon earlier this week that Israel had violated the ceasefire about 100 times.

"I think fundamentally, both parties, that is to say Israel and Hezbollah, through the Lebanese government, wanted and continue to want the cease fire," said Blinken.

"But we have to make sure that it's upheld. And we're determined to do that," he added.
