1 killed and roughly 100 National Guard troops injured in Kiev, following grenade attack by far-right protesters

Ukrainian police have detained a man suspected of attacking a crowd of riot control officers with a grenade earlier today at a protest by far-right nationalists against the Parliament's vote in support of granting greater autonomy to the separatists regions in Donetsk and Lugansk. The attack has already claimed the life of one police officer, and another three remain in critical condition, Kiev's mayor, Vitali Klitschko, told Hromadske.tv.

Video has appeared online apparently capturing the moment of the grenade attack. At roughly 1:09 in the clip below, a large explosion shakes the ground and sends police limping away from the site of the blast.
