• Middle East crisis – live updates

Israel has launched some of the heaviest airstrikes to date on Beirut, the Lebanese capital, before an expected ceasefire in its war with Hezbollah.

The Israeli military began attacking areas of Beirut dominated by the Lebanese militia early on Tuesday before issuing a flurry of 20 evacuation calls – its widest warning to civilians since hostilities escalated into full-blown war in late September.
