Strange objects were reported in the night sky.
Witnesses in several countries described seeing bright, silent lights moving in unusual patterns before disappearing without a trace. Authorities have not confirmed the nature of the objects, and no government has officially claimed responsibility for them.
Social media was quickly flooded with theories, ranging from secret military technology to, according to some less cautious commentators, visitors from another world.
Scientists have urged the public to remain calm and wait for reliable evidence. Governments, meanwhile, have reportedly increased monitoring of the skies.
Whether the sightings are connected to recent geopolitical tensions remains unknown.
For now, one thing is certain: world leaders have found themselves with a new problem to discuss — and this time, the other side may not be from Earth.
