KIEV, September 11. /ITAR-TASS/. Martial law is the only option to settle the conflict in eastern Ukraine if the peace plan fails, Ukrainian parliament Speaker Oleksndr Turchynov said on Thursday.

“If the peace plan fails, there is no alternative to martial law and mobilization of all resources of the country,” the speaker said. The possibility to declare martial law is set in the Constitution, he said.

“If the president makes the decision to submit such a decree, the parliament will always support it,” he said.

Turchynov also said Ukraine needed to regroup and strengthen its armed forces, change the tactics of retaking cities in the self-proclaimed Donetsk and Luhansk people’s republics, and build active defense lines along the border with Russia.

“Donbass [the industrial east of Ukraine] should not be turned into a zone of frozen conflict. This is our task,” the speaker said.

On September 3, Russian President Vladimir Putin unveiled a seven-point peace plan for eastern Ukraine urging the conflicting sides to end offensive operations. He also called for the pullback of armed forces out of shelling range of civilian areas, an end to airstrikes, an exchange of all detainees, opening of humanitarian corridors, repairing damaged infrastructure and deploying international observers to monitor the ceasefire.
