A gas mask lies among other debris at a barricade where U.S. Secretary of State was visiting the Shrine of the Fallen in Kiev on March 4, 2014. The Shrine of the Fallen, located on Institutska Street, honors the fallen "Heroes" of the "Heavenly Sotnya" (Hundred). Over the course of the EuroMaidan protests, almost 100 protesters were killed by police. Most of them died on February 20 killed by sniper or automatic weapons fire on Institutska Street. US Secretary of State John Kerry arrived in Kiev Tuesday for talks with Ukraine's new interim government, amid an escalating crisis in Crimea. His visit came as the United States said it would provide $1 billion to financially-stricken Ukraine as part of an international loan. With the Black Sea peninsula of Crimea under near complete control by pro-Russian forces, US officials said Moscow could face sanctions within days.
