MINSK, October 9. /TASS/. A constitutional reform involving all regional and all political forces in Ukraine is needed to achieve sustainable settlement of the crisis in that country, Russian Foreign Minister Sergey Lavrov said on Thursday.

“The main thing now is to launch a dialogue which is starting between representatives from Kiev, the Luhansk and Donetsk People’s Republics. This is step one,” Lavrov said. “A next step is a comprehensive political dialogue, a constitutional reform with the participation of all regions and all political forces in Ukraine.”

“This is a key task, if we are speaking about a sustainable settlement of the Ukrainian crisis,” he added.

Lavrov earlier Thursday said All Commonwealth of Independent States countries welcome the role played by the Minsk accords over Ukraine.

Special status to regions in eastern Ukraine

Ukraine's parliament passed a law granting a special self-rule status for certain districts in Donetsk and Luhansk regions. The special status is designed for three years.

The special status law was stipulated by the Minsk agreements reached in early September in the Belarusian capital on the basis of Russian President Vladimir Putin’s seven-point plan proposed two days before.

The parliament also passed a law prohibiting persecution and punishment of participants in the armed conflict in the country’s southeastern Donetsk and Luhansk regions. However, speaking earlier about the bill on amnesty for participants of hostilities in Ukraine’s embattled eastern regions, President Poroshenko said it will not be applied to certain types of crimes.

Those, who committed crimes under Criminal Code articles stipulating premeditated murder, terrorism, attempts to assassinate a state official, a law enforcement officer, a judge, rape, looting, vandalism and some other articles designed to ensure state integrity, will not be subject to amnesty
