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, which opposes Somalia’s UN-backed government, says it carried out the attacks.
The attack on the palace began when militants failed to stop at a checkpoint, resulting in an exchange of gunfire, state-owned media say.
Then a parked car blew up near a hotel, security officials say.
However, al-Shabab said it had targeted “a national security forces’ base”.
A spokesman for the group said both car bombs had involved suicide bombers.
The group said the attacks had killed 15 soldiers, without providing any evidence.
A police spokesman told Reuters news agency: “There were many military soldiers who guarded the street adjacent to the palace.”
The attacks came a day after the security minister warned of a possible car bomb attack in Mogadishu, Somalia’s Radio Simba reports.
They are the latest in a series of high-profile incidents attributed to al-Shabab, which once controlled Mogadishu before being forced out by African Union troops in 2011.
In October last year, more than 500 people were killed by a truck bomb in the city.
Officials blamed al-Shabab for the bombing but the group never said it was behind the attack.
