Two car bombs killed at least 17 people in Somalia's capital Mogadishu on Saturday, the police said, two weeks after a huge truck bomb killed hundreds of civilians in the city.
Islamist group al Shabaab claimed responsibility for the attacks on Saturday.
A suicide car bomb was rammed into a hotel, Nasahablod Two, about 600 metres from the presidential palace, and then armed militants stormed the building, the police said. A few minutes later, a car bomb exploded near the former parliament house nearby.
Ali Nur, a police officer, told Reuters 17 people, mostly policemen, had died in the blasts. "Security forces have entered a small portion of the hotel building ... the exchange of gunfire is hellish," he said.
The police personnel who died had been stationed close to hotel's gate. The dead also included a former lawmaker, he said. Fighting continued to rage inside the hotel after the blast and the police said the death toll was likely to rise.
Abdikadir Abdirahman, director of Amin ambulances, told Reuters the emergency service had carried 17 people injured from the hotel bombing.
A huge cloud of smoke rose over the scene and a Reuters witness saw over a dozen wrecked cars and bloodstains in front of the hotel. Sporadic gunfire could be heard.
Islamist group al Shabaab, responsible for scores of such attacks in the country's long civil war, said it carried out Saturday's bombings.
"We targeted ministers and security officials who were inside the hotel. We are fighting inside," Abdiasis Abu Musab, the group's military operations spokesman, told Reuters.
He said the hotel belonged to Somalia's internal security minister, Mohamed Abukar Islow.
Al Shabaab is fighting to topple Somalia's internationally-backed government and impose its strict interpretation of Islam's sharia law.
Bombs in Mogadishu two weeks ago killed at least 358 people, the worst such attacks in the country's history, igniting nationwide outrage.
Another 56 people are still missing, believed to have been burnt without a trace. Al Shabaab was widely suspected, but has not claimed responsibility after thousands of Somalis poured onto the streets to protest.
Al Shabaab's attacks are growing in frequency and size, as a 22,000-strong African Union peacekeeping force prepares to begin withdrawing.
In 2016, 723 people died in 395 bomb attacks in Somalia, according to a report produced earlier this year by Nairobi-based think tank Sahan Research.
