This is very eerie. I can not stress enough, these are two separate stories.

They happened exactly one day apart. They are both from Egypt.

And lastly, the death toll from BOTH events is six people dead; one surviving.

Very spooky.
==========================

First, as reported a few days ago [1], fumes from an Egyptian sewage canal kill 6, injure 1...

... and then an Egyptian cesspit claims six more lives [2] the next day.

Eerie!
