Bamako - A security official in Mali says 22 people have been arrested after stockpiles of weapons were found in various homes nearly a month after a military coup.
Colonel Diamou Keita made the announcement on national television late on Wednesday following criticism of this week's arrests, which included several high-ranking officials from the government overthrown in the coup.
Keita said the weapons found did not belong to Mali's military and that the country is facing "a new threat".
The European Union and United Nations have called on Mali's military junta to release the detainees.
The junta had agreed to hand over power to an interim civilian government, though some fear the latest arrests show the military has no intention of leaving politics.
