'Confusion on MH17 crash points to importance to thorough investigation'

"If the passenger jet was shot down, there only a limited number of weapons in the region that could have been responsible. One possibility is the Buk surface-to-air missile system.

Several former Soviet countries use the weapon, including Ukraine. It has the ability to hit up to 24 targets at the same time within a distance of 45 kilometers, and reaching an altitude of 25 kilometers. 

Its missiles travel at up to 1,200 meters per second. But as yet, there is no confirmation that this weapon system was the cause of the crash. For more RT is joined by former UK army officer Charles Shoebridge."
