Nation in mourning as siege hotel yields clues

Mali started three days of national mourning on Monday for the victims of the jihadist siege at a luxury hotel that left 19 people dead in the capital, Bamako, with neighboring Senegal, Mauritania and Guinea joining in a show of solidarity.

The investigation was "following several lines", with no certainty about the number and nationality of the perpetrators of the attacks, which have been claimed by two separate jihadist groups.

Gunmen went on the rampage at the Radisson Blu hotel from morning on Friday, shooting in the corridors and taking 170 guests and staff hostage.
