"I am shocked at this reprehensible terrorist attack. I offer my sincere condolences to the families of the victims and wish those injured a speedy recovery. This heinous act once again shows that urgent progress is required towards the formation of the Government of National Accord and the activation and rebuilding of Libyan security forces," Kobler was quoted as saying by the United Nations Support Mission in Libya (UNSMIL).
Libya has been in a state of turmoil for years after the Arab Spring protests in early 2011 led to a civil war, and a western military intervention helped Islamic rebels overthrow the country’s long-time leader Muammar Gaddafi.
The instability that has plagued Libya since 2011 has facilitated the emergence of numerous militant groups, including IS. The Islamic State is a designated terrorist organization that is outlawed in Russia and many other countries.
