The upsurge of violence continues in Afghanistan. Today a bomb tore though a minibus carrying Afghan labourers to a US military base in Kandahar. Around 10 people were killed in the attack, which occurred during the southern city’s rush hour.The Taliban has claimed responsibility for the bombing, which comes as NATO prepares to take over from US troops in the volatile south of the country – the heartland of the Taliban, who have copied the tactics of rebels in Iraq by launching a campaign of suicide bombings. Today’s attack is the latest incident in the worst wave of violence to hit Afghanistan since US forces toppled the Taliban regime in 2001. A US-led offensive against the insurgents is currently underway. German forces stationed in the country are not taking part, but could be brought in to help if unrest continues to spread.
