“We have agreed with Elmar Mammadyarov that…we will discuss joint measures to ensure that this outrageous action will not go unanswered,” Lavrov added.
Lavarov and Mammadyarov are Russia's and Azerbaijan's respective foreign ministers. So what was the event that so outraged Russia, and "will not go unanswered"? Human rights? Oil? Terror? erm..
Russian Foreign Minister Sergei Lavrov condemned the disappearance of votes awarded by Azerbaijan to Russian singer Dina Garipova at the recent Eurovision Song Contest as “an outrageous action,” and vowed on Tuesday that Russia would respond to the incident. (source)
