BAMAKO - Three Chinese citizens were killed in a hostage-taking situation at a hotel in Mali's capital Bamako, the Chinese Embassy confirmed to Xinhua on Friday.

Four other Chinese citizens were rescued from Radisson Blu hotel in Bamako, said embassy officials.

According to Wang Yi, political counselor of the Chinese embassy in Mali, the rescued Chinese are in stable condition.

At least 22 people were killed on Friday after Malian forces staged a rescue mission to free hostages held by gunmen at the luxury hotel in Bamako.

There were no more hostages held at Radisson Blu hotel, said security minister Salif Traore, hours after gunmen stormed the hotel and held 170 people hostage, many of them foreigners.

But security sources said Malian forces were in the process of securing the hotel as gunmen were still holding out inside the seven-storey building.

Security sources said two attackers had been killed, but it remained unknown if the attackers were among the 22.

The rescue operation by Malian special forces received support from MINUSMA, the UN peacekeeping mission in Mali, U.S. and French troops.

The gunmen entered the hotel, which houses 190 rooms and sheltered 140 people of different nationalities, on a car with diplomatic plate, said Traore.

Some hostages succeeded in escaping by their own means while the majority of them were rescued by the special forces.

Jihadist Al-Murabitoun group based in northern Mali has claimed responsibility for the hotel attack.

The group was also responsible for a shooting attack on a restaurant popular with foreigners in Bamako on March 7 this year, which killed five people and wounded nine others.
