Thousands of Somalis gathered Friday to pray at the site of the country’s deadliest bombing. Last Saturday a truck bomb exploded on a busy street in Mogadishu, killing what is now believed to be 358 people.
As Somalis in the capital city paid their respects, the Somali prime minister said Somalia’s president will announce a “state of war” against the al-Shabab extremists the government blames for the bombing.
President Mohamed Abdullahi Mohamed is expected to announce the new offensive Saturday, according to the Associated Press.
Army spokesman Captain Abdullahi Iman told the Associated Press that the new offensive was to involve thousands of troops to try to push al-Shabab fighters out of their strongholds in the Lower Shabelle and Middle Shabelle region, where they are believed to have planned their attack on Mogadishu.
Several suspects have been arrested and are being questioned.
“Our security agencies have more detailed information about the blast as there are people we have arrested,” said Internal Security Minister Mohamed Abukar Islow, “but we will let you know when we are done with our investigations.”

Also Friday, the U.S. military said it launched a drone strike on al-Shabab, resuming its own fight with the militant group.
Somalia’s information minister reported late Friday that 56 people were still missing from the Mogadishu blast, which wounded 228 people. Of the injured, 122 had been airlifted to Turkey, Sudan and Kenya for treatment.
