At least four people have been killed and dozens more injured after jihadist militants attacked a popular hotel in Somalia’s capital, Mogadishu.
Witnesses have told the BBC of hearing multiple explosions and heavy gunfire coming from the Villa Rose hotel near the presidential palace.
Security forces are battling to regain control of the building after it was stormed on Sunday evening.
The al-Qaeda affiliated group al-Shabab has said it carried out the attack.
The Villa Rose Guest hotel is popular with government officials and several ministers have confirmed being rescued.
At least one minister, Mohamed Ahmed, is reported to have been injured while another, Environment Minister Adam Aw Hirsi, told reporters he had survived the attack.
Al-Shabab has continued to carry out attacks in central and southern Somalia despite recent government troops backed by African Union forces and local militias retaking areas previously captured by the group.
An unknown number of assailants, armed with explosives and guns, were involved, police officers told Reuters news agency.
One eyewitness described hearing a “huge blast, followed by a heavy exchange of gunfire”.
“We were shaken,” Ahmed Abdullahi, who lives close to the scene, told the news agency. “We are just indoors, listening to gunfire.”
Some government officials were rescued from Villa Rose after using windows to escape, said police officer Mohammed Abdi.
In August, three months after taking office, President Hassan Sheikh Mohamud pledged “total war” against the Islamist militants following an attack on another popular Mogadishu hotel. More than 20 people died.
Two months later, twin car bomb explosions near a busy junction in Mogadishu killed at least 100 people. Al-Shabab also said it was behind that attack.
President Mohamud subsequently mobilised the Somali army and government-backed clan militias in a bid to take villages and towns from al-Shabab, which controls large swathes of the country.
BBC Africa correspondent Andrew Harding recently spent time with the so-called “lightning” brigade, which is funded by the US and plays a central role in the uprising against al-Shabab.
The militant group’s central aim is to topple Somalia’s government and establish its own rule based on a strict interpretation of Islamic law.
