Russian accounts claimed that Russian FSB detained "Ukrainian saboteurs" and "terrorists" near Armiansk. The ensuing gunfight left one FSB officer and a suspect dead. A number of individuals were detained, including Yevhen Panov, who is described by Russian sources as a Ukrainian military intelligence officer and leader of the sabotage group. The group was allegedly planning terror attacks on important infrastructure in Armiansk, Crimea. Ukrainian media reported that Panov was a military volunteer fighting in the east of the country, however he has more recently been associated with a charitable organization. Russia also claimed that the alleged border infiltration was accompanied by "heavy fire" from Ukrainian territory, resulting in the death of a Russian soldier.

Transition and aftermath Economic implications Initially after the annexation, salaries rose, especially those of government workers. This was soon offset by the increase in prices caused by the depreciation of the ruble. Wages were cut back by 30% to 70% after Russian authority became established. Tourism, previously Crimea's main industry, suffered in particular, down by 50% from 2014 in 2015. Crimean agricultural yields were also significantly impacted by the annexation.
