**UPDATE**
It's being reported that the thick black clouds of smoke are being caused by a large fire in an auto garage right beside the Vatican.
Thick, black clouds of smoke have been seen towering over the Vatican.
No details have been released from the Vatican yet on the cause, but it's being reported that a "loud boom" was heard.
