A US military jet crashed in mountainous territory in eastern Afghanistan, where there is a heavy Taliban presence, the Pentagon confirmed Monday, rejecting the insurgents’ suggestions that it was shot down. Afghanistan US Forces spokesman Colonel Sonny Leggett confirmed in a statement that the aircraft was a US Bombardier E-11A, a type of jet used as a military airborne communications node in the region. “While the cause of crash is under investigation, there are no indications the crash was caused by enemy fire,” Leggett said.
