On departure from an airport in Afghanistan. We were being jammed electronically on departure frequency during the whole departure. We initially were given a straight out climb; finally followed by a right 90 degree turn and I think a climb to FL 200. The pilot flying dialed in FL210 that I did not catch. I questioned the altitude both of the Pilot Flying and ATC. I saw FL205 before we started down to FL 200. This is the best that I recall.
As a result of electronically compromised communications the flight crew of a B767 began a climb to FL210 before able to obtain a correction and returned to FL200 as cleared.
