I admit I only skimmed the article, and I haven't been keeping up with the day to day goings on over there, but off the top of my head even if there is a ceasefire in effect I can think of a couple reasons they might still be doing it

They want the ceasefire extended, or are prepping for another ceasefire further down the line after things resume

General raising awareness

They believe one or both sides aren't holding up their end of the ceasefire agreement and want to hold them accountable

They've now pivoted to the next issue regarding the conflict, like what can be done with the time the ceasefire has bought, what the next steps should be after it ends, how to bring about an end to the war, what should happen after the war, etc.
