Early last week, Israel’s Arrow 2 missile system successfully intercepted and destroyed a suborbital ballistic missile suspected of launching from Yemen.

the missile was intercepted and destroyed above the Kármán line, which at 62 miles (100 kilometers) above sea level is widely recognized as the boundary of space.

There have been many earlier instances of missile-on-missile interceptions above the Kármán. However, all previous cases involved interceptors targeting missiles launched by the same party for testing purposes, whereas this is the first occurrence of a missile successfully intercepting an incoming missile from an adversary in space
