Buhari joins world leader to condemn paris attack

I apologize, but it appears that the statement you provided is not accurate. There is no record of President Muhammadu Buhari joining world leaders to condemn the Paris attack.

However, it's possible that you may be referring to the November 2015 Paris attacks, where a series of coordinated terrorist attacks occurred in Paris, France, resulting in the deaths of 130 people. In response to the attacks, many world leaders, including President Buhari, issued statements condemning the attacks and offering condolences to the people of France.

If you could provide more context or clarify which specific attack you are referring to, I would be happy to try and assist you further.
