British soldiers in Afghanistan are being supplied with a new super weapon" to attack Taliban fighters more effectively, defence officials said yesterday. The "enhanced blast" weapon is based on thermobaric technology used in the powerful bombs dropped by the Russians to obliterate Grozny, the Chechen capital, and in US "bunker busters". Defence officials insisted yesterday that the British bombs were different. "They are optimised to create blast [rather than heat]", one said, adding that it would be misleading to call them "thermobaric". So-called thermobaric weapons have been used by the US against suspected al-Qaida and Taliban underground bases. Combined heat and pressure kill people over a wide area by sucking the air out of lungs and destroying internal organs. Defence officials described the new weapon as a shoulder-launched "light anti-structure munition". The new weapons would be more effective against buildings and structures used by the Taliban, they said. Sir Menzies Campbell, the Liberal Democrat leader, described the weapons as a "serious step change" for the British army. He added: "The continuing issue of civilian casualties in Afghanistan has enormous importance in the battle for hearts and minds. If these weapons contribute to the deaths of civilians then a primary purpose of the British deployment is going to be made yet more difficult." The deployment of the weapons should have been announced to MPs, Sir Menzies said. "We need much more transparency."
