GHAZNI (Reuters/AFP) - Four foreign servicemen and at least three Afghan soldiers were killed in separate incidents of pre-election violence across the country, officials said on Tuesday. With a presidential and provincial poll just nine days away, violence has escalated across Afghanistan, making 2009 the deadliest year since the Taliban were ousted in 2001. US military spokeswoman Captain Elizabeth Mathias confirmed that three servicemen with the International Security Assistance Force (Isaf) reported killed in separate incidents in the south were American, while Polands defence ministry said one of its nationals had been killed and four wounded in the east. In southern Kandahar province, a bomb tore into a minibus killing nine Afghan civilians. Men, women and a child were killed when a roadside bomb blew up the minivan in which they were travelling through the southern province of Kandahars Maiwand district, heartland of the Taliban militia. Another four people were wounded in the blast, a doctor from Kandahar citys main hospital told AFP. Six of them are men, two are women and there is a child. The bodies were put in a car by the police there and sent to the hospital, said the doctor, Daud Farhad. A similar blast hit a civilian car in adjacent Zhari district, wounding five more people, the district chief said. Unknown gunmen killed two elders and wounded three others including a member of a public awareness unit of the election commission in Takhar province on Tuesday, said Abdul Qodus, an election commission officer. In an interview, the top commander of US and Nato forces in Afghanistan on Tuesday vowed coalition forces would prevail in the war and said he was open to reconciling with rank-and-file insurgents. We will win. The Taliban wont win. But we will also have to deal through good and bad days, and good and bad months, Gen Stanley McChrystal told US National Public Radio. The US commanders comments came after he told the Wall Street Journal in an interview published Monday that the Taliban had momentum in the war and that NATO-led forces had to stop their initiative. The Gen said he supported President Hamid Karzais view that many insurgents were motivated by money and not ideology. I would absolutely be comfortable with fighters and lower level commanders making the decision to reintegrate into the Afghan political process under the Afghan constitution, he said. As for reconciling with higher level figures in the insurgent leadership, McChrystal said, Thats clearly up to him (Karzai). Asked about security for the elections in the volatile Helmand province, where thousands of US forces have deployed, McChrystal said most Afghans would have the opportunity to vote.
