Iran is using bulldozers at the Ukrainian plane crash site, which could make it impossible to find out what really happened

• A Ukrainian airplane crashed shortly after taking off in Iran on Tuesday, killing all 176 passengers onboard.
• US, British, and Canadian intelligence later determined it was shot down by an Iranian surface-to-air missile, which Iran has strongly denied.
• Physical evidence at the crash site could prove what really happened. But images from the scene show workers seeming to move chunks of debris with heavy machinery.
• One expert said this could make it "next to impossible" to properly investigate the crash.
• Iran has also been reluctant to hand over the black boxes from the Boeing 737-800.

Images and reports from the crash site, just outside Tehran, show at least one bulldozer working in the debris at the site, where the Boeing 737-800 crash-landed on Tuesday, killing all 176 people on board.
