The wounded are rushed to hospitals in the Somali capital Mogadishu, after a deadly truck blast that killed over 70 people on Tuesday.
The attack was claimed by al-Qaeda linked rebels al Shabaab.
It was the deadliest single attack by the group since launching an insurgency in 2007.
Witnesses said a truck exploded at the gate of a compound housing government ministries, where students and parents had gathered to await the results of scholarship exams.

"I was waiting for my exam results at the Ministry of Education this morning, I saw a vehicle crashing into the front check point of the building and it blew up. I was with my brother when it happened but I don't know where he is now."
A spokesman for al Shabaab warned civilians to stay away from government buildings and military bases, saying "more serious blasts are coming."
The group want to oust the UN-back transitional government and impose their own harsher version of sharia law.
Tuesday's attack comes as the government embarks on a 12 month political road map which is supposed to lead to elections in August next year.
