A quick google scan confirms what I had understood - that it's NOT the first such claimed incident - there was apparently one in the USA in 1954, for example, and even a claim in the UK in 2004 - both alleged to have caused injuries to single individuals by an actual encounter with extraterrestrial material but it is perhaps the first authenticated example to cause injuries on such a wide scale.
It seems to me, from the videos shown, that the damage has primarily been caused by blast wave overpressure, rather than from actual impact of extraterrestrial material. In general, of course, these effects are no different from the lethal combination of extensive glazing and any explosive event. Also, the report of a collapsed factory roof would fit with overpressure impact.
It seems to me that reports of people being actually hit by extra-terrestrial material, as the ones above claim, have, in many cases, to be treated rather sceptically.
Near Earth Object specialists, whose competence I respect, are saying that the orbital trajectories of the Siberian meteor/meteorite and that of asteroid 2012 DA14 are totally different, and that this is a total coincidence.

Subject: Meteorite Disaster
The events today (once verified) would be the first fully confirmed report that I have been able to find of human casualties from meteorites--in all of human history. See http://www.ilankelman.org/disasterdeaths.html<http://www.facebook.com/l.php?u=http%3A%2F%2Fwww.ilankelman.org%2Fdisasterdeaths.html&h=CAQEZJ13eAQEtGYkUi6B-aReJzQ60ejV6IHpZwcrMj5kUcw&s=1> and click on "Astronomical Phenomena" for details. My work, though, is far from comprehensive, so if anyone can identify previous examples, then please let me know, because I will update this page over the weekend.
Given the nuclear power plant and nuclear waste storage facility in the impact vicinity, we have yet more evidence that "negligible probability events" must to be taken seriously. And remember that a minuscule time difference in the impact could have hit many other locations--or bypassed the planet entirely.
Which leads to a random question: could the shower be linked to today's asteroid near-miss or not at all?
