The US has urged Israel to ensure the safety of UN peacekeepers in Lebanon, after Israel fired on UN bases in the south of the country.
On Thursday, two peacekeepers were wounded when an Israeli tank fired on UN facilities in the south.
Two more peacekeepers were injured in a separate explosion earlier - the IDF says it's investigating how it happened.
Meanwhile, rescue workers are searching through rubble after two Israeli air strikes hit central Beirut on Thursday.
Lebanon's prime minister says the 22 people killed in the attacks, which came with no warning, were all civilians. Another 117 people were injured. Israel has not commented.
