The death toll from a massive blast at Beirut’s port has risen again to 137, as the Lebanese army took control of the site on the first day of a two-week state of emergency.

The new casualty figures on Thursday morning include at least 5,000 injured and a health ministry spokesman said dozens were still missing. “This toll is not final,” he said.

As volunteers worked with the army to clean up shattered streets, buildings and hospitals, the government said it had formed an investigation committee to look into the explosion, which appears to have been set off by 2,750 tonnes of ammonium nitrate that had been stored at the port since 2014.
