Ten Nato soldiers were killed in a wave of violence in Afghanistan yesterday, the deadliest day this year for the international forces.
In the worst single incident, five American service personnel were killed in a roadside bomb blast in eastern Afghanistan, the US command said.
Two more US soldiers were killed in separate attacks — one a bombing in the south and the other by small arms fire in the south.
Three other Nato service members from other countries were also killed in other attacks.
In addition, an American contractor died in a suicide attack against the police training centre in Kandahar city, the US Embassy in Kabul said.
No details were immediately available for the operations in which the Nato troops died.
The American contractor, who was not identified, and another person were killed when a team of three suicide bombers attacked the gates of the police training centre.
The bloodshed came as Taliban insurgents step up bombings and attacks on Nato forces ahead of a major operation in the southern Taliban stronghold of Kandahar, which Washington hopes will turn the tide of the war.
