Boko Haram leader claims blast in Nigeria's Lagos - AFP
"A bomb went off in Lagos. I ordered the bomber who went and detonated it," the French news agency, which is usually the first to get hold of Shekau's videos before they distributed online, said.
Authorities said the blast was an accident caused by a gas canister, but security sources told Reuters that was a cover up meant to avoid panic in the southwestern city of 21 million people.
