Nine people have been killed in an airstrike on a multi-storey building in a residential district in Beirut, the Lebanese health ministry has said. The attack targeted an apartment in a building that houses an office of the Health Society, a group of civilian first responders affiliated to Hezbollah. It comes after Iran launched dozens of missiles into Israel on Tuesday night. Israel's military said it had killed 15 Hezbollah militants in south Lebanon today. Israel has mostly concentrated its airstrikes in south and eastern Lebanon, as well as the southern suburbs of Beirut, where Hezbollah has a strong presence.
