• Live updates: Israel-Hezbollah ceasefire comes into effect

A highly anticipated ceasefire aimed at ending the 14-month-old war between Israel and Hezbollah officially came into effect early on Wednesday morning, hours after Joe Biden hailed the “historic” moment.

The ceasefire officially began at 0200 GMT – 4am in Lebanon – after the heaviest day of raids on Beirut, including a series of strikes in the city’s centre, since Israel stepped up its air campaign in Lebanon in late September before sending in ground troops.

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.

After 20 people including 15 first responders killed in Douris, rescuers ask why state service was targeted

All the corpses had been recovered but still the rescuers sifted through the rubble. A paramedic carried a sack with him, filled with the charred remains of his colleagues. Every few feet he stopped and knelt down, assessing. In the twisted mess left behind by the Israeli airstrike, it was hard to distinguish between flesh, earth and the life-saving equipment that had melted in the heat of the blast.

The night before, on Thursday, an Israeli jet had dropped a bomb on the salon of the Douris civil defence centre on the outskirts of the ancient Lebanese town of Baalbek, killing 20 people, including 15 first responders. Five were rendered unrecognisable by the force of the explosion. On Friday afternoon, emergency workers were still collecting bodily remains to be taken for DNA analysis.
