The militant group said 16 of its members were killed in Friday’s attack in Beirut, which Lebanon’s health minister said left a total of 31 people dead.

More than 60 people were also wounded in the attack, of whom 15 remain hospitalized. Search and rescue are ongoing and the number of casualties will likely rise.

U.N. peacekeepers in Lebanon urged immediate de-escalation as hostilities rumbled on at the Lebanese-Israeli border on Friday, following Israel's most intense airstrikes in nearly a year of conflict with the Iran-backed Hezbollah.
