I found the first part where the guy was digging in the rubble, then later searching the tunnel to be inconclusive. I couldn’t tell who or what was going on.
However, the second part, where the guy is handcuffed in his underwear, surrounded by soldiers, then later on it looks like the same guy being herded through a building… that doesn’t look good. Someone below mentioned a possible prisoner swap. I don’t think prisoner swaps are handled like that.
