Eight Nato troops killed in Afghanistan

Insurgent attacks in Afghanistan killed eight Nato service members in one of the deadliest days for the military coalition this year, signalling the start of what many fear will be a particularly violent fighting season as President Barack Obama looks to start drawing down troops, authorities said Sunday.
The spate of attacks happened Saturday, when two separate bomb blasts in the south killed three soldiers and a suicide bombing by a Taliban sleeper agent killed five Nato service members at a US base in the east.
Fighting usually increases in Afghanistan as the weather warms and insurgents climb back over the mountainous border with Pakistan.
