The NOTAM is pretty standard for overflying a small-arms / light-weapons conflict zone. Mortar and medium artillery can loft up to 30,000 ft on high charges.
It obviously didn't consider the use of dedicated anti-aircraft weapons. But even primitive shoulder-launched MANPADS like the original Strela-2 have been recorded striking easy targets over 24,000 ft ( a Hunter over Oman in the 1970s ).
