Czech Republic–Russia relations
Czech foreign minister Jakub Kulhánek issues Russia with an ultimatum to return all of the Czech diplomats it had expelled from the Czech embassy in Moscow, following a series of reciprocal moves between the two countries since April 17 to expel each other's diplomats after the Czechs discovered Russian intelligence involvement in the 2014 Vrbětice ammunition warehouses explosions. Kulhánek threatens to expel more diplomats from the Russian embassy in Prague if the ultimatum is not met.
