The Malian army captured two people linked to Ansar Dine group (Arabic translation of "supporters of the religion") and seized evidence linking them to planned attacks, security sources said on Sunday.

Ansar Dine was part of an alliance of gunmen that helped seize Mali's desert north after a Tuareg uprising in 2012 but was ousted by a French military operation a year later.

The group this week claimed responsibility for a series of recent attacks across Mali's south and west, including the capital Bamako, formerly deemed safe.

"An army patrol arrested two men in possession of military material and compromising documents," said one of the sources, adding that the men were captured in the central region of Mopti and taken to Bamako.

He said the documents contained a message from Ansar Dine's Tuareg leader Iyad Ag Ghali to an accomplice in the south about future attacks.

The southern accomplice has not yet been identified, he said, adding that others had been called in for questioning based on the intelligence gathered so far.

A second security source said a total of six people had been detained for questioning, including two women, part of a push to dismantle Ansar Dine's network.

Armed groups and the Malian government signed a peace agreement in June designed to stop uprisings in the north, but Ansar Dine was not part of it.
