According to a memorandum to the bill, "measures on the legal regime of martial law include internment (forced settlement) of nationals of a foreign state which threatens to attack or carries out aggression against Ukraine."
On January 27, the Ukrainian parliament adopted a bill recognizing Russia as an aggressor country.
In February, the amendments to the bill on martial law were endorsed by the National Security and Defense Council of Ukraine, which stressed the necessity of the new document being in line with current realities.
In late December 2014, President Poroshenko said that a martial law would be introduced if the ceasefire agreement on eastern Ukraine was violated. "No one will doubt even for a minute", the Ukrainian President said at the time.
The parties agreed on a ceasefire and the withdrawal of artillery from the frontline of contact, as well as the exchange of prisoners.
The ceasefire regime, which has been in force in Donbass since February 15, is generally being observed, although though there are reports of shootings in some areas.
