Each year in Warsaw, Poland, traffic halts and pedestrians stop on the streets for one minute, to remember a WWII uprising that killed 200,000 soldiers and civilians.

The Warsaw Uprising was an effort to end the Nazi occupation of Poland that lasted for 63 violent days and destroyed the city. This year, the anniversary of the uprising that began on August 1, 1944 took to social media where the city broadcast some commemoration events live, according to the Washington Post.

But one of the most touching documents to emerge from the tribute was a viral video filmed in 2011 and released last July 30. The footage shows a bustling city that turns still, as people rise and sirens begin to wail.

The video has collected more than 2.8 million views since it was uploaded last year.

Israel holds a similar tribute each year at the end of April to remember the six million Jews who died during the Holocaust. The sound of sirens across Israel for two minutes marks the anniversary, called Yom Hashoah.

A video uploaded this year shows cars rumbling past a busy street in Eilat. As the sirens being to sound, a vehicle screeches to a halt at an intersection and its passengers, along with others, step out to stand in memory of those lost.
