Two workers for the International Committee of the Red Cross have been kidnapped in northern Mali, the ICRC in Mali said on Twitter on Saturday. It said the abductions took place between the northern cities of Gao and Kidal - long a hotspot for militant and militia violence. "We confirm the kidnapping of 2 of our colleagues this morning ... We ask for no speculation about the incident so as not to hinder its resolution," the ICRC in Mali said. It did not disclose the names or nationalities of those kidnapped.
