Sources: Car bomb hits northern Mali town of Kidal

BAMAKO - A car bomb exploded in the remote northern Malian town of Kidal on Tuesday, Malian military and Tuareg rebel sources said, the second such attack in the town in recent days as Islamist rebels step up a guerrilla campaign.
French forces have been stationed in Kidal since driving out al Qaeda-linked fighters late last month as part of a campaign against militants who had seized the northern two thirds of the country.
