Students were among the 23 people killed when a pair of suicide car bombings struck a government building and a nearby market in Galkayo, Somalia, Sunday, according to CNN.
One bomber reportedly rammed his vehicle into the main gate of the building, local police Capt. Abdi Hassan told CNN.
As first responders rushed to the scene, a second car bomb went off.
An eyewitness told Voice of America, "When the first explosion occurred, I was in a nearby tea restaurant. I came out to see what has happened. I saw a woman driver with a red head scarf speeding towards us, and then, I immediately crossed the road . The second explosion occurred."
After the car bombs detonated, attackers stormed the government building, exchanging fire with security forces, Hassan told CNN.
Puntland's Mudug regional Governor told Voice of America that the town has recently come under the attack of "ruthless terrorists."
Al-Shabab, a terrorist group within the country, has claimed responsibility for the attacks.
Voice of America reported that the attacks are believed to be a response to military operations conducted by U.S.-trained Somali Special forces.
This attack is just one in a series of similar attacks. In July, six people were killed when two suicide car bombs exploded in Mogadishu and 12 were killed in an attack on the capital's Addee International Airport, according to CNN.
