A famous Guinean singer who was among 170 people taken hostage on Friday by Islamist gunmen in the Radisson Blu hotel in Mali's capital, Bamako, said he heard attackers in the next room speaking English.

"I heard them say in English 'Did you load it?', 'Let's go'," singer Sékouba 'Bambino' Diabate, who was freed by Malian security forces, told Reuters in Conakry. "I wasn't able to see them because in these kinds of situations it's hard."
