The header of this post is slightly incorrect, insofar as the aircraft is not actually off the runway but still very much on it.
According flightglobal, MLG collapse on landing due suspected hydraulic failure. Aircraft suffered substantial damage, including a totalled LH engine.
Aircraft was TC-ACB, as mentioned an ACT bird operating on behalf of DHL, and is probably a write-off, not least because it's blocking the only runway in Bagram and NATO is rather keen on getting that very important airbase back up running. I suspect it'll be pulled off the runway with little regard to preserving whatever integrity of the aircraft is still intact.
