Kiev, Ukraine (AP) It’s a day of national mourning in Ukraine, where the death toll from an apartment building explosion has reached 26.
Rescuers who have pulled 21 people from under mounds of concrete and glass are continuing the search for more survivors but say conditions are working against them.
Temperatures have dipped into the low 20s.
The searchers are pausing every hour to listen for cries for help.
More than 60 people were registered as living in the destroyed section of the apartment building.
Officials believe oxygen canisters in the building’s basement exploded but they haven’t ruled out other possible causes.
