Is the new Nigerian law promoting paedophilia?

Here's how it happened. The Nigerian senate on Tuesday July 16th pegged the official marriage age in Nigeria as 18 years when they amended the constitution. Then Former Zamfara Governor, now Senator, Sani Yerima, who married a 13 year old Egyptian girl in 2010, opposed the age restrictions saying it was anti-islam. For some reason the Senate agreed with him and made an about turn.
