A suicide bomber blew himself up late Saturday night, the second such attack in this northern Malian city since Friday, said a Malian army officer.

The most recent attack occurred Saturday at about 11pm at a checkpoint to enter the city, said Capt. Daouda Diarra. The bomber set off the explosive belt he was wearing, killing himself and injuring a Malian soldier, said Diarra.

The explosion occurred in the same place where an earlier suicide bomber killed himself on Friday morning.

The bomber's remains could be seen, including his head in a wheelbarrow.
