Story highlights Putin calls for "humanitarian pause" as violence worsens in Aleppo

Syrian rebels have stepped up attacks to try to break the regime's siege of rebel-held eastern Aleppo

(CNN) Russian President Vladimir Putin has unilaterally declared a 10-hour "humanitarian pause" for Aleppo on Friday, a senior Russian official said Wednesday.

"A decision was made to introduce a humanitarian pause in Aleppo on November 4 from 9 a.m. to 7 p.m. (3 a.m. to 1 p.m. ET)," chief of Russia's General Staff Valery Gerasimov said in a statement on Wednesday.

The latest truce comes as fighting in the beleaguered city grows ever more deadly, with rebel assaults on regime-held parts of Aleppo claiming 84 lives over the weekend, the Syrian military said Monday.
