More than 60 still missing after Beirut mega-blast
"The number of dead is 154, including 25 who have not yet been identified," the official told AFP. "In addition, we have more than 60 people still missing."
The health minister said on Friday that at least 120 of the 5,000 people who were injured on Tuesday are in critical condition.
Officials have said a huge shipment of hazardous ammonium nitrate had languished for years in a warehouse at the port and somehow caught fire, leading to Tuesday's earth-shaking blast.
However Lebanese President Michel Aoun rejected any international probe into the catastrophic blast, saying he saw it as an attempt to "dilute the truth".
Aoun admitted on Friday he had known about the huge stockpile of explosive material stored at the port nearly three weeks before it blew up. He claimed to have ordered action be taken about it at the time, although the top leader also said he had no authority over the facility.
The World Health Organization has called for $15 million to cover immediate health needs.
