Putin just put out a statement video which you will notice was at roughly 2:30 in the morning so you can tell he is feeling some heat though based on what he said he still doesn't give a shit.

He starts off blaming Ukraine stating if Ukraine had not resumes military options that he knows for sure this would not had happened. All parties in the region of Ukraine need to take their responsibility for the event.
Then he states No one has the right to use this event for gain. The World should unite not divide. He also comments that not enough is being done to ensure safety at the crash site and a proper investigation which you can obviously take as another swipe at Ukraine.
He ends it vowing to continue to push for peace talks to end the military actions by Ukraine and get them to the peace tables
