MAIDUGURI, Nigeria (Reuters) - At least 10 people were killed on Saturday in a bomb blast in the northeast Nigerian city of Maiduguri, witnesses said, in a region where the Islamist sect Boko Haram is pursuing a bloody insurgency.

The bomb exploded at around 6 p.m. in a busy market area in Ajilari-Gomari near the city's airport, and the final death toll was likely to be higher because dozens of people were trapped in the rubble, two witnesses and a police source said.
