Official warns of security threats after Mali hotel assault

The prosecutor in charge of investigating last week’s deadly assault on a luxury hotel in Mali’s capital urged residents to keep an eye out for suspicious behavior, warning of heightened security threats as officials struggled to piece together details of how the attack was plotted and executed.

“People need to start watching what is happening with their neighbors,” Boubacar Sidiki Samake told The Associated Press on Tuesday, adding that future attacks could be better prevented only if Malians “changed their behavior.”

Samake, though, provided very little new information about the probe of Friday's assault that killed 19 people.

On Monday, state television broadcast the photos of two gunmen killed in the attack and urged anyone with information to come forward.

The previous day, the first Islamic extremist group to claim responsibility _ Al-Mourabitoun, or The Sentinels _ issued an audio recording purporting to identify the gunmen, using names that suggested they were Malian. But officials have yet to confirm their identities and said they did not know if the attackers were based in Bamako before the attack.

Samake said the gunmen were spotted to the west of the Radisson Blu hotel at 6 a.m. on Friday morning about an hour before the attack began, sitting with two suitcases containing the Kalashnikov assault rifles they used in the attack.

On Tuesday, a United Nations police official displayed the assault rifles to journalists in Bamako, but said they had been handled by too many people to yield useful fingerprints.

“With the serial numbers... we can trace whether these come from the Malian army stock, which was looted in 2012, or if they were imported illegally,” said the official, who gave only his first name, Laurent, in line with the policy of his division.

Officials are still trying to determine how exactly the victims were killed in the hotel, Samake said.

Noting that Islamic extremists also shot up a Bamako bar popular with foreigners in March, Samake said security threats in the city were “very high.”

On Monday, U.N. spokesman Stephane Dujarric said the U.N. mission in Mali had offered help with the investigation and had joined Malian security forces in conducting night patrols in the city.

Also on Tuesday, Mali’s U.N. mission reported that a civilian staff member was killed in the northern region of Timbuktu when a vehicle drove over an explosive device. The incident occurred just before noon about 25 kilometers (15 miles) west of Timbuktu, mission spokesman Olivier Salgado said.

It is the same region where, last July, gunmen ambushed a U.N. convoy and killed six peacekeepers from Burkina Faso in an attack claimed by al-Qaida in the Islamic Maghreb.

U.N. Secretary-General Ban Ki-moon condemned Tuesday’s attack and reaffirmed “that such attacks will not alter the determination of the United Nations to support the Malian people and the peace process,” his spokesman said.

Northern Mali fell under control of Islamic extremists in 2012, prompting a French-led military intervention in early 2013 that drove them from cities and towns. The north remains insecure, however, and the U.N. mission in Mali is the deadliest in the world, with more than 40 peacekeepers killed since it was established in April 2013.

The story has been corrected to show that the number of peacekeepers killed in Mali is more than 40, not nearly 60.
