The death toll from an Israeli airstrike that targeted a house in northern Lebanon has risen to 21, according to the Lebanese Health Ministry. Another eight were injured, the ministry said. It added that DNA tests are being carried out on remains to identify them. The Israeli strike hit a house in the area of Aito where displaced people from southern Lebanon were sheltering, a Lebanese security source said. It was the first time this area has been hit by Israeli. Lawmaker Michel Moawad, who is from the affected region, said from the site that a Hezbollah member was targeted.
