There was some breaking news last night out of Manchester, United Kingdom. Eyewitnesses said it appeared to be some sort of explosion. It took place at or near an Arianna Grande concert in Manchester Arena. British police initially said at least 19 people were killed and that dozens of others, around 50, were injured.
Emergency workers rushed to what was described as a chaotic scene. There were several videos like this that showed people panicking and running.
When we produce this show, there were still more questions than answers, but British officials said they were treating this as a terrorist incident.

Another story we're covering, what's known as the Doomsday Vault has been breached.
This is an emergency storage facility for seeds — more than 500 million of them from all around the world. It would allow people to recreate food supplies in case there's some sort of global catastrophe. The vault's carved into a side of a mountain Svalbard, a Norwegian archipelago about halfway between Norway and the North Pole.
The company that manages the vault says water has gotten in, that it breached the entrance to the vault and sit about 50 feet into part of an access tunnel. The seeds themselves were not harmed.
So, how did this happen?
Regardless of when you're watching this show on Tuesday, the temperature in Svalbard is below freezing. The vault's management company says the breach occurred during an unusually warm and rainy October. They just made it public. Officials are waterproofing the walls inside the tunnel entrance to better protect the vault.
