All day Friday, Russians visited the Dutch embassy in Moscow to pay their condolences for the downing of Malaysian Airlines Flight MH17 over Ukraine as it was flying from Holland to Malaysia. Many left flowers.

The typed note here says, in Dutch: "Not all Russians are murderers and terrorists."

This note reads: "In our country there are a lot of good people who love other people. Forgive us for all the rest."

Some left notes in English: "We are very very very very sorry! What a terrible shame!"

President Barack Obama on Friday called on Russia to do more to end the conflict in east Ukraine.

It is increasingly believed that the airliner was downed by a missile launched from separatist-held territory in east Ukraine. "It is not possible for these separatists to function…without sophisticated equipment, sophisticated training. And that is coming from Russia," Obama said. Vladimir Putin, meanwhile, has put the blame on Ukraine: "Without question, the state over whose territory this took place, bears responsibility for this awful tragedy," he said.
