Bamako - The official leading the investigation into the attack on a luxury hotel in Mali's capital is urging residents to keep an eye out for suspicious behaviour and warns of heightened security threats.
Prosecutor Boubacar Sidiki Samake on Tuesday provided scarce new information about the probe of Friday's assault that killed 19 people, saying authorities are still trying to determine how exactly the victims died.
He also said officials had little information on the two gunmen killed in the attack.

On Monday state television broadcast their photos and officials urged anyone with information to come forward.
The attack was claimed by Islamic extremists. It was the second attack to hit Bamako this year. Samake said Malians must "change their behaviour" and watch over their neighbourhoods more closely to prevent future violence.
