The death toll in a truck bombing in Somalia in October now stands at 512, according to the committee investigating the tragedy.
The toll had been reported as 358. Even at the lower number, the bombing was the deadliest in Somalian history.
No group claimed responsibility for the attack. Somalian officials have blamed the al-Qaida-linked al-Shabab extremist group, which has been trying to overthrow the government and has deployed bomb attacks against government, military and civilian targets.
The committee, known as the Somali Emergency Operation Center, was established to investigate the October 14 bombing in Mogadishu. The government was to receive the report this week, but as of Saturday it had not commented.
In response to the October attack in Mogadishu's Kilometre 5 neighborhood, the U.S. military expanded its operations against al-Shabab and increased the frequency of airstrikes targeting jihadist leaders.
The U.S. military now has more than 500 personnel in Somalia.
