A fire broke out at the National Archives in Kew, London this morning at about 12:30 GMT/7:30 EST. The building is home to over 11 million British treasures, a host of which can be viewed here, and the source of the flame has not yet been revealed. According to the Archives' Twitter, no one has been injured and all documents remain intact, though the fire is still being fought by over twenty firemen.
We can confirm all records and people are safe and were unharmed.
