Russian President Dimtry Medvedev has condoled with the government of Nigeria over the recent terror attack in Yobe and Borno during which more than 100 people died. \"I vigorously condemn these inhuman extremist acts which have absolutely no excuse,\" Medvedev said in a condolence message to President Goodluck Jonathan on Wednesday. These crimes committed in Nigeria reaffirm the necessity to further consolidate the international effort in fighting terrorism, he added. The coordinated attack which was launched in Damaturu and Maiduguri on Friday also destroyed property. The Boko Haram sect members claimed responsibility.
