A hotline set up to allow Russian soldiers to surrender is already getting calls, Ukraine claims.

Ukraine says its "I Want to Live" hotline guarantees confidentiality and humane treatment.

Some Russians have been scrambling to avoid Putin's newly announced partial mobilization.

Russian men drafted to war by President Vladimir Putin's recent mobilization announcement are using a Ukrainian hotline to ask how they can give themselves up, according to Ukraine's Ministry of Defense.

Andrii Yusov, spokesperson for the department, said during a televised briefing on Monday that there had been a strong response to the "I Want to Live" hotline, according to Ukrainian newspaper Ukrainska Pravda.

The hotline was announced by Ukraine's Ministry of Defense on September 19, two days before Russian President Vladimir Putin announced the mobilization of reservists to the battlefield.

Yusov said the hotline has received "a lot of calls" from recently drafted Russians, and even some who haven't yet been mobilized, per the newspaper.

Yusov added, per the paper: "They're calling and asking 'What should I do if I get called up? What do I have to do, what's the right way to surrender?'"

Yusov's comments have not been independently verified.

But Putin's announcement sparked protests nationwide and has prompted some Russians to take desperate measures to be called up.

Putin had earlier promised that he would not take this step, which brings the reality of the war to Russians accustomed to civilian life.

Flights to several countries sold out after the announcement, and according to The Guardian, some are paying up to ?27,000 for private jets out of Russia. Satellite images also showed traffic at Russia's borders from people trying to leave the country.
