Now, Khorsabad as Well?

The Iraqi government is now claiming that ISIS has now begun destroying the ruins of the Assyrian city of Khorsabad (Dur al-Sharrrukin) as well.

Again, there are only the government reports. The city was founded by Sargon II (722-705 BC) as his capital, but abandoned undwer his successor Sennacherib, who ruled from Nineveh instead.
