DONETSK, December 12. /TASS/. The Russia-Donbass allied forces are advancing along the whole engagement line, acting Head of the Donetsk People’s Republic Denis Pushilin said on Monday.

"We see units of our [allied] forces advancing along the whole engagement line," Pushilin said in his video address.

According to him, this advance "may be at some stretches [of the engagement line] about 100-200 meters a day, or important 10-20 meters, if it improves the positions."

Pushilin told TASS earlier that over 300 residential localities in the republic had been liberated from the Ukrainian military.

Developments in Ukraine

The situation along the line of engagement in Donbass escalated on February 17. The Donetsk and Lugansk People’s Republics (DPR and LPR) reported the most massive bombardments by the Ukrainian military back then, which damaged civilian infrastructure and caused civilian casualties.

On February 21, President Vladimir Putin announced that Moscow was recognizing the sovereignty of the Donetsk and Lugansk People’s Republics. Russia signed agreements on friendship, cooperation and mutual assistance with their leaders. Moscow recognized the Donbass republics in accordance with the DPR and LPR constitutions within the boundaries of the Donetsk and Lugansk Regions as of the beginning of 2014.

Russian President Putin announced on February 24 that in response to a request by the heads of the Donbass republics for assistance he had decided to carry out a special military operation in Ukraine. The DPR and the LPR launched an operation to liberate their territories under Kiev’s control.

From September 23 to September 27, the Donetsk People’s Republic and the Lugansk People’s Republic as well as the Kherson Region and the Zaporozhye Region held a referendum where the majority of voters opted to join Russia.

On September 30, Russian President Vladimir Putin and the heads of the DPR, the LPR, and the Zaporozhye and Kherson Regions signed treaties on their accession to Russia. Later, the State Duma and the Federation Council (the lower and upper houses of Russia’s parliament) approved legislation on ratifying these treaties, as well as federal constitutional laws on the accession of the four regions to Russia.
