They initially numbered 1,000, but subsequently thinned.^[3] In an address on the Ukrainian national television channel, interim President Oleksandr Turchynov stated that the current unrest in eastern Ukraine was "the second wave" of a Russian operation to destabilise Ukraine, overthrow the government and disrupt planned elections and represented an attempt by Russia to "dismember" Ukraine.^[1] He vowed to launch a major "counter-terrorism" operation against separatist movements.^{[4][unreliable source?]}
