US President Joe Biden has said he is "absolutely, positively" urging Israel to stop firing at UN peacekeepers during its conflict with Hezbollah in Lebanon, following two incidents in 48 hours.
On Friday, the Israel Defense Forces (IDF) said its troops were responsible for the incident, in which two Sri Lankan soldiers for the UN Interim Force in Lebanon (Unifil) were injured.
IDF soldiers operating around the Unifil base in Naqoura identified a threat and opened fire, the Israeli army said, adding the incident would be investigated "at the highest levels".
On Thursday, two Indonesian Unifil soldiers were injured falling from an observation tower after an Israeli tank fired towards it.
The leaders of France, Italy and Spain issued a joint statement condemning Israel's actions, saying they were unjustifiable and should immediately come to an end.
Sri Lanka's foreign ministry said it "strongly condemns" the IDF attack which injured two of its soldiers.
The head of UN peacekeeping said there was reason to believe some firing on UN positions in southern Lebanon had been direct, though he did not ascribe responsibility for the incidents.
"For example we have a case where a tower was hit by a fire and also damages to cameras at one of the positions - which obviously to us very much looked like direct fire," Jean-Pierre Lacroix told the BBC's Newshour programme.
