12:02 PM PT -- South Korean officials have gone on record to say at least 120 are dead so far from the crowd surge in Itaewon.
Multiple people are feared dead after dozens of lifeless bodies required CPR in South Korea Saturday during what appears to be a mass gathering that turned into a crowd surge.
Several videos and photos are circulating on social media right now showing countless people laid out on the floor in the streets of Itaewon -- a popular neighborhood in Seoul -- and receiving chest compressions from both first responders and bystanders alike.
The images are scary ... as a lot of these folks don't seem to have any signs of consciousness -- and you can tell how frantic of a scene it is by the reaction.
Reports on the ground say upwards of 100 people were injured total -- with a significant amount purportedly having gone into cardiac arrest as well. There are signs multiple fatalities could result from this -- some photos show cops putting tarps over what seem to be dead bodies ... but there's no official count of lives beyond just 2, per NYT.
The reason all these people congregated here is because it's one of the biggest Halloween get-togethers there in Seoul -- reports say tens of thousands of people had packed into the relatively tight alleyways, which some speculate likely triggered a stampede of some sort.
One rumor floating around -- which hasn't been substantiated -- is that the crowd crush was caused by folks rushing toward a bar there in Itaewon after word of a celeb sighting ... although it's unclear who exactly it might've been, if anyone.
