Mogadishu just can't seem to catch a break as insurgents continue to pull off deadly assaults in the heart of the capital.

The Somali city was hit with another terrorist attack on hotel Sunday, where over 29 people were killed during a siege lasting nearly 12 hours, Reuters reports.

This prompted the government to let go of two top security officials—Intel Chief Abdullahi Mohamed Sanbalolshe and Commander of Police Adbihakim Saiid.

Al Shabbab has claimed responsibility for the attack, which took place ahead of a planned gathering between the federal government and regional states to try to defuse tensions between both entities. Government officials convened at the hotel to talk strategy.

Three militants were captured alive and two others self-detonated themselves after they were shot, police say. It's suspected that some militants may have disguised themselves and escaped with the residents who were rescued from the hotel.

"They had the uniforms of security forces, even though they did not have ID cards," Information Minister Abdirahman Omar Osmantells Reuters.

As of Monday morning, Somali authorities have imposed a daytime ban on the movement of large trucks and road tankers inside Mogadishu in efforts to improve security.

"Trucks and tankers cannot pass...from 7:00 am to 8:00 pm. This is to ensure security and (to offer) a solution to the complaints of the public," Tabid Abdi, the capital's mayor, says in a statement. "Any truck or tanker driver who does not comply will be fined $1,000."
