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 has launched a strike on Beirut for the second time in days, further testing the shaky ceasefire with Hezbollah struck four months ago.

An already fragile ceasefire between Israel and the Lebanese militant group Hezbollah appeared to be on shakier ground after rockets fired from Lebanon into northern Israel triggered Israeli airstrikes in the suburbs of Beirut.
