from RT.com: A Russian Proton-M rocket carrying three GLONASS navigation
satellites crashed soon after takeoff from Kazakhstan’s Baikonur
cosmodrome.

Immediately after takeoff, the rocket swerved to one side, tried
to correct itself, but instead veered in the opposite direction.
It then flew horizontally and started to come apart with its
engines in full thrust.

Making a huge arch in the air, the rocket plummeted back to earth
and exploded on impact close to another launch pad used for
Proton commercial launches.

The crash was broadcast live across the country and fears of a
possible toxic fuel leak immediately surfaced following the
incident. While no such leak has been confirmed, the rocket was
initially carrying over 600 tons of toxic propellants.

There have reportedly been no casualties to surroundings
structures and the town of Baikonur was not affected.
