Three United Nations peacekeepers suffered light injuries on Sunday, the UN said, after a blast near their vehicle close to Lebanon's southern border, where Hezbollah and Israel have traded near-daily fire.

"Earlier today, three peacekeepers on patrol were lightly injured when an explosion occurred near their clearly marked UN vehicle in the vicinity of Yarine, in south Lebanon," the UN Interim Force in Lebanon (UNIFIL) said in a statement. "All peacekeepers in the patrol returned safely to their base. We are looking into the incident," it added.

Earlier Sunday, Lebanon's state-run National News Agency had reported that "Israeli enemy warplanes" struck the village of Dhayra, about one kilometer from Yarine, "resulting in injuries." A UNIFIL source told AFP the explosion that injured the peacekeepers was probably a nearby air strike, but "not a direct hit."
