After two UN peacekeepers were wounded by an Israeli strike near their watchtower in south Lebanon, US President Joe Biden said he was asking Israel not to hit Unifil forces, Reuters reports.

Russia said it was “outraged” and demanded Israel refrain from “hostile actions” against peacekeepers. The United Nations said both were from Sri Lanka.

The Israeli military said air raid sirens sounded in central Israel and two drones were detected from Lebanon late on Friday. It said it successfully intercepted one drone but one building in Herzliya sustained some damage. No casualties were reported.

The Israeli military said two peacekeepers had been hurt by Israeli fire as it was engaging Hezbollah and expressed “deep concern”. It said they had been warned hours earlier to take shelter.

In a sign of a spreading conflict, a Syrian security source said that the US-led coalition in Syria had targeted Iran-linked sites near northeastern Syria’s Deir el-Zor airport on Friday night.
