By Tara Brady PUBLISHED: 04:01 EST, 2 July 2013 | UPDATED: 04:32 EST, 2 July 2013 A Russian rocket carrying three navigation satellites worth around $200 million and 600 tonnes of highly toxic fuel exploded into a fireball moments after take-off. The explosion led to a large spill of heptyl, a highly toxic rocket propellant, but there were no reports of casualties or of any immediate threat to nearby settlements. State-run Rossiya-24 television showed footage of the Proton-M booster rocket veering off course seconds after lift-off at the Russian-leased Baikonur launch facility in Kazakhstan on Tuesday.
