Gen. Dempsey’s plane hit by shrapnel in Afghan rocket attack

The plane that carried Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, on a trip to Afghanistan was damaged by shrapnel from rocket fire on Tuesday, according to multiple media reports.

Dempsey was not in the plane at the time of the attack and remained unharmed, although two workers at the airfield sustained minor injuries. Dempsey left Afghanistan later Tuesday on a different aircraft.

The general was in Afghanistan to meet with coalition and Afghan leaders, including the commander of NATO forces in the country and the commander of the Afghan Army. His C-17 Globemaster was parked at Bagram Air Field, outside Kabul, when a pair of rockets was launched in its direction.

A NATO helicopter was also damaged in the attack.

Dempsey's visit comes amid a spike in "green-on-blue" attacks, where Afghan military members being trained and equipped by allied forces have attacked Americans. On Sunday, the death toll in attacks by Afghan military and police rose to 40 for the year, with another 69 troops wounded. Attacks in the past two weeks alone have left 10 American troops dead.

"We've been watching with deep concern these so-called green-on-blue attacks, where you have Afghan individuals, some of whom are actually enrolled in the Afghan military ... attacking coalition forces," President Obama said during a press briefing on Monday.

Obama pledged to reach out to Afghan President Hamid Karzai to find ways to stem the attacks.

"Obviously, we're gonna have to do more, because there has been an uptick," said Obama.
