BAMAKO/KIDAL, Mali, Feb 4 Mali's defence
ministry said on Saturday the armed forces had killed about 20
northern separatist rebels and taken a dozen more prisoner
during two days of clashes in the Timbuktu region.
Tuareg-led MNLA rebels made no immediate comment.
Sporadic heavy weapons fire was heard also on Saturday near
the northern town of Kidal, northeast of Timbuktu, which the
rebellion says it is in the process of attacking.
Veteran Tuareg insurgents and men returning from Libya's war
last year are fighting to create an independent state in north
Mali. They have gained ground in a three-pronged advance,
scattering thousands across Mali's north and beyond its borders.
Mali's defence ministry said that the rebels had been killed
during two days of operations in Timbuktu, one of three regions
targeted by the MNLA. There were no losses on the government
side, according to the statement.
The government gave no further details on the clashes but a
Malian military source and a local journalist said most of the
rebels were killed when air force helicopters attacked rebel
positions near the town of Niafunke on Saturday.
Hama Ag Sid'Ahmed, a Europe-based spokesman for the rebels,
confirmed that military operations were taking place near
Niafunke but said it was too early to give a toll.
Residents in Kidal, a town in north Mali, said that they had
heard sporadic heavy weapons fire overnight and through Saturday
morning. Sid'Ahmed said the firing came from an MNLA attack on
Kidal, which would be the most significant target yet since
clashes erupted in mid-January.
"We will take the two military camps and occupy the town,"
However military sources in Kidal and the capital, Bamako,
said the sound of gunfire came from army units warding off a
rebel attack following rumours that the MNLA were due to strike
Civilians, fearing an attack, have been fleeing Kidal by bus
in recent days. Some Tuaregs say many of their community have
also fled Bamako, in the south, fearing reprisals after violent
demonstrations this week.
About 3,500 people had crossed westwards into Mauritania,
said a Mauritanian official, who asked not to be named.
The International Committee for the Red Cross said on Friday
that nearly 10,000 people had fled into Niger after fighting
between the army and armed groups in the area around Menaka and
Anderamboucane, in the northeast of Mali.
One refugee in Niger, Aminatou Sango, said everyone tried to
flee. "I left my very old mother and one of my daughters as they
could not walk. I am here alone."
The rebels say they are fighting to secure the independence
of Azawad - Mali's three northern regions, Kidal, Timbuktu and
Gau. The government accuses the rebels of atrocities and
collaborating with al Qaeda, a charge the MNLA rejects.
The ICRC said that some refugees were being looked after by
local families while others had set up makeshift camps.
The aid group said the refugees were crossing into a desert
region of Niger that is expected to be hit hard by a food crisis
