"I have been shocked by this terrorist attack in Burkina Faso and the death of a Ukrainian family - three adults and one child," Klimkin wrote on his Twitter account early on Sunday morning. The killed child was only nine years old, he said. It was reported that on Friday evening two car bombs were detonated near Ouagadougou's Splendid Hotel, which is frequently used by UN staff and Western tourists, and then a group of masked gunmen attacked the building. The siege was claimed by Al Qaeda in the Islamic Maghreb (AQIM) and its branch Al-Mourabitoun. The attack in Ouagadougou claimed the lives of at least 23 people from 18 states, Western media reported on Saturday, citing a source in Burkina Faso's security services.
