An Israeli air strike on Beirut's southern suburbs has killed a Hezbollah official and three other people, Lebanon's health ministry says, putting further pressure on a fragile ceasefire between Israel and the Lebanese armed group. The strike also injured seven people, the health ministry said.

Israel launched strikes on southern Lebanon on Saturday, killing at least seven people, authorities here said, in response to rockets fired from across the border earlier in the day. The exchange was the largest since the fragile ceasefire between Israel and Hezbollah went into effect late last year.
