In an attempt to peacefully end the conflict ravaging his country, Ukrainian President Petro Poroshenko has ordered a weeklong ceasefire to allow mercenaries to leave eastern Ukraine.

Poroshenko announced the ceasefire Friday at a military base in Svyatogorsk and laid out a peace plan he hopes will begin the process of resolving the conflict. As part of his plan, he introduced a 14-point peace plan that would establish a 6-mile-long demilitarized zone between Russia and Ukraine. This would allow Russian and Ukrainian mercenaries, believed to be part of the fighting, to escape, according to The New York Times.

Ukraine has accused Russia of covertly supplying arms to the rebels, a charge the latter has denied. However, fighting has continued despite the ceasefire, which neither the rebels nor Russia believes is sincere.

"The plan lacks a key part: a call for dialogue," Russian Foreign Minister Sergey V. Lavrov said Saturday from Jidda, Saudi Arabia. "We are alarmed and concerned that, simultaneously with the proposal of this plan, the activity of the so-called anti-terrorist military operation is increasing."

Rebel fighters from the new autonomous regions of Luhansk and Donetsk also said they will not stop fighting. Alexander Borodai, prime minister of the Donetsk People's Republic, does not recognize the ceasefire and has instead asked Russia to send in peacekeepers in fear of a "humanitarian catastrophe" at the hands of the Ukrainians.

Amid claims that the ceasefire is a ruse, rebel forces attacked and tried to capture Ukrainian posts near the Russian border overnight Saturday. Rebels also attacked an air defense base at Avdiyivka. The first two outpost attacks, at Izvareno and Uspenka, led to firefights with rebels and wounded nine Ukrainian men. Rebel casualties weren't reported.

Reuters reported that Ukrainian troops repelled multiple rebel attempts to seize strategic points.

Meanwhile, Russia is continuing to flex its military muscle: On Saturday, President Vladimir Putin mobilized 65,000 troops in central Russia.

Putin said the mobilization is part of a military drill, but the troop movements have raised tensions in the region. Despite the distance between the Ural Mountains and Ukraine and the ceasefire, fighting in eastern Ukraine continues and, according to the Telegraph, has spilled over into Russia. The FSB, the KGB's successor, claimed shelling and fighting has crossed the border and demanded an apology from Kiev.
