Six NATO soldiers including four Brits, three Afghan civilians and four border police officers were killed in latest series of attacks in Afghanistan, officials said Wednesday, according to dpa. Two NATO-led International Security Assistance Force (ISAF) soldiers were killed and 10 were wounded during a patrol in south-eastern Paktika province, close to border with Pakistan on Wednesday, the ISAF said in a statement. "These soldiers died and were wounded trying to help bring peace and security for the Afghan people," Brigadier General Carlos Branco, ISAF spokesperson, was quoted in the statement. The statement did not disclose the nationalities of soldiers. Most of the NATO forces in eastern Afghanistan are US soldiers. Meanwhile, four British soldiers were killed and one wounded in a roadside bomb blast in southern Helmand province on Tuesday. In another incident, four Afghan border police were killed and three were wounded in a roadside attack in Alisher district of south- eastern Khost province, Sher Ahmad, a police official in the province said. Three civilians were killed and 10 were wounded in an attack that took place in Dil Aram district of Farah province on Wednesday afternoon when a convoy of NATO-led forces was passing by, Abdul Raouf Ahmadi, spokesman for police forces in western region, said. "The suicide bomber who had explosives around his body attacked the convoy, killing himself and three civilians," Ahmadi said, adding that 10 injured civilians were taken to provincial hospitals. He said there were no casualties among the foreign soldiers. Taliban spokesman Qari Mohammad Yousif Ahmadi took responsibility for the attack, which he said had been carried out by one of their fighters, Mullah Omar. The US military said its forces would destroy a Chinook helicopter in eastern Nuristan province after the chopper had "hard landing." "No service members were seriously injured in the landing. The cause of the incident is currently under investigation," the statement said. Taliban-led violence is on the rise in Afghanistan with militants mostly rely on use of suicide and roadside attacks. Around 2,000 people - mostly insurgents and Afghan civilians, but also more than 70 international forces - have been killed so far this year.
