The UN’s peacekeeping mission in Lebanon (Unifil) has accused the IDF of hindering the work of its forces and dropping an “unknown chemical” in the country over the weekend.

A Unifil spokesperson said that its operatives had been warned to “stay away and remain under cover” on Sunday while the drop of a “non-toxic chemical substance” was completed, forcing them to cancel “over a dozen activities”.

This was done close to the so-called “Blue Line” – the UN-recognised boundary between Israel and Lebanon.

"Peacekeepers could not perform normal operations near the Blue Line along about a third of its length and were only able to resume normal activities after over nine hours,” the spokesperson continued.
