Looks like varanus griseus(aka sand monitor, Iranian desert monitor. They are a CITES I animal. You might want to post the pictures over at www.varanus.nl for an exact ID. I believe a few years ago some army documentary over in Iraq was seen by one of the varanus biologists and they saw a monitor that had not been classified in the footage. I believe they were able to investigate the area and classified a new species. Interesting stuff. Thanks for showing the pictures.
