Plus
Iran, April 2003 -- hit by US missiles during bombing of Iraq, killing at least one person {2}
Pakistan, 2002-03 -- bombed by US planes several times as part of combat against the Taliban and other opponents of the US occupation of Afghanistan {3}
China, 1999 -- its heavily bombed embassy in Belgrade is legally Chinese territory, and it appears rather certain that the bombing was no accident (see chapter 25)
France, 1986 -- After the French government refused the use of its air space to US warplanes headed for a bombing raid on Libya, the planes were forced to take another, longer route; when they reached Libya they bombed so close to the French embassy that the building was damaged and all communication links knocked out.{4}
