The U.S. military says a roadside bomb killed two U.S. soldiers when it exploded near their military vehicle during a deadly day in Afghanistan.
A military spokeswoman says another coalition soldier and an Afghan interpreter were wounded in the blast Tuesday in eastern Nangarhar province.
Separately, a suicide bomber rammed a car into a convoy of coalition troops in Khost province bordering Pakistan, wounding three U.S. soldiers. And in the eastern province of Ghazni, an explosion outside an Islamic seminary (madrassa) killed three people and wounded at least eight others.
Afghan authorities say the blast occurred as explosives were being attached to a motorbike in preparation to carry out an attack at another location. One man was taken into police custody.
The Taleban has carried out a series of suicide bombings in southern Afghanistan in recent months, but few of the attacks have occurred in the east of the country.
Meanwhile, military and diplomatic officials from Pakistan, the U.S. and Afghanistan met near the Pakistani capital to discuss regional cooperation and coordination in the war against terrorism.
Senior generals from the three countries also reviewed the security situation along the Afghan-Pakistani border and efforts to fight militants. The gathering in Rawalpindi was the first to be attended by representatives of NATO-led troops, which are set to take control of security in southern Afghanistan next month.
