The Biden administration is concerned the fragile ceasefire in Lebanon could unravel after Israel and Hezbollah exchanged fire in recent days, U.S. officials say. Why it matters: The ceasefire announced last Tuesday ended more than a year of fighting between Israel and Hezbollah.

The Israeli army has attacked several targets in Lebanon, killing two people, as a shaky ceasefire holds with the pro-Iranian Lebanese militia, Hezbollah. The Israeli military said on Monday that the attacks were in response to ceasefire violations by Hezbollah.
