Two large explosions in Somalia's capital city Mogadishu have killed at least 18 people and injured dozens.
One attack took place at the gates of the presidential palace, while a second hit near offices of the national intelligence agency.
Officials say five of the attackers were shot and killed.
The Islamist militant group al-Shabab claimed responsibility for the attacks.
The explosions shattered a months-long period of calm in Mogadishu, which is often the target of attacks by the al-Shabab extremist group. They also came a day after Somalia's interior minister warned of an explosives-laden vehicle somewhere in the capital.
