BEIRUT: Urgent calls for foreign nationals to leave Lebanon grew on Sunday with France warning of “a highly volatile” situation as Iran and its allies ready their response to high-profile killings blamed on Israel. Lebanon’s Iran-backed Hezbollah movement, which has traded near-daily fire with Israeli forces since the Gaza war broke out in October, announced its fighters had fired a barrage of rockets at Israel’s north overnight. The Israeli military said 30 projectiles were launched from Lebanon, with most of them intercepted.
