Car stopped while driving and struggling to turn its engine - is it seized?

My car suddenly stopped (seemed like it stalled) with no warning lights or noises. The AA suggest seized engine as can't jump start and the starter won't manually move. Any ideas if it could be anything less complex than a seized engine?

Does read as if it has seized. If three of you can't push it while it's in 2nd gear then it is seized.
