This really hinges on the video, which could be hoaxed, we just don't know. If it's real, in this vid we see something moving faster than the fireball and striking it, causing it to fragment. Is it true? Well, it's a region where Russia could have such weapons available. Quite amazing if it is true.

The plasma explosion of a bolide http://www.brighthub.com/science/space/articles/115001.aspx is what is being claimed at Chelyabinsk and Cuba.
"Bolides that Explode
Exploding bolides are also called detonating fireballs. The reason why some bolides explode has to do with the composition of the object. If the internal composition is water-ice then the bolide will likely explode. This is because as the meteor enters the Earth's atmosphere and begins to descend, ram pressure generates a shock wave produced by the compression of gases in the Earth's atmosphere. This ram pressure causes the meteor to heat up which causes the water-ice inside the meteor to boil and when it reaches a critical stage it explodes violently, fragmenting the object into much smaller pieces. The smaller pieces will burn up through the atmosphere, seldom causing any injury to humans or damage to property."
The above scenario leaves very few fragments as in the comet explosion over Tunguska in 1908 http://www.physics.purdue.edu/people/faculty/yekim/1908_Tunguska_Kim.pdf . Since the entire projectile is the explosion it tends to leave very few fragments, unlike Chelyabinsk which left 2 masses almost equal to the original in size.
"Christopher Chyba and others have proposed a process whereby a stony meteorite could have exhibited the behavior of the Tunguska impactor. Their models show that when the forces opposing a body's descent become greater than the cohesive force holding it together, it blows apart, releasing nearly all its energy at once. The result is no crater, and damage distributed over a fairly wide radius, all of the damage being blast and thermal.
Three-dimensional numerical modelling of the Tunguska impact done by Utyuzhnikov and Rudenko in 2008 supports the comet hypothesis. According to their results, the comet matter dispersed in the atmosphere, while the destruction of the forest was caused by the shock wave." http://en.wikipedia.org/wiki/Tunguska_event
All of the above references show virtually very little to no fragments remain from bollide explosions. But, at Chelyabinsk we have an explosion more similar to an explosion on solid rock with large fragments emerging.
It's no secret that Chelyabinsk is home to top secret research and is virtually surrounded by other top secret research cities.
"Chelyabinsk has had a long association (since the 1940s) with top-secret nuclear research, though this is more properly applicable to Chelyabinsk Oblast as a whole, as nuclear facilities such as Chelyabinsk-70 are, or were, located far outside the city.
"Chelyabinsk is an industrial city about the same size as New Orleans. Andrey says it's surrounded by other off-limits cities where top secret work is done,..." http://www.fox8live.com/story/21221039/a-local-man-from-chelyabinsk-reacts-to-meteor-strike-near-his-family
Enter: "Anti-Ballistic Missile - Gazelle:
53T6 (NATO reporting name: ABM-3 Gazelle, previously SH-08) is a Russian anti-ballistic missile which works as part of the A-135 anti-ballistic missile system. It was designed in early 1980s and put in service in 1995.
The missile is able to intercept incoming re-entry vehicles at a distance of up to 80100 km. 53T6 is a two-staged solid-propellant missile armed with 10 kt nuclear warhead. The missile is about 10 meters in length and 1 meter in diameter. Its launch weight is 10 tons.
The 53T6 missile is kept in silo-based launch container. Prior to launch its cover is blown off.
It was last tested in October 2009. The Gazelle is a follow-on development of the ABM-1 Galosh." http://en.wikipedia.org/wiki/53T6
Unverified close up of meteor, if verified would be documented proof of missile. http://www.youtube.com/watch?feature=player_embedded&v=WaQIPBqoQ-Q
Watch the Flash and the Blast Wave - also note the timing is consistent with flash and then a pressure wave - not some sonic boom from breaking the sound barrier: http://www.guardian.co.uk/world/video/2013/feb/15/meteor-shards-russia-explosion-video
"Experts have been scouring a 50-foot hole in a frozen lake on the outskirts of Chelyabinsk, in the Urals, believed to have been carved out when the fireball crashed to the ground.
