What the...? This was shot in late January; in Lagos, Nigeria, traffic is entirely stopped while people look at a UFO.
The official caption has it as "Unidentified Flashing Object" - they say it's some mysterious flashing thing that appears, mysteriously, at traffic intersections around the city.
And, seriously, that's all the information given. I tried to get more details and all I learned is that traffic like this is routine in Nigeria. Apparently they have terrible gridlock problems, such that if there is a problem somewhere the entire city winds up locked.
