"A distinction must be made between legitimate resistance and uncalculated adventures undertaken by elements inside [Lebanon] and those behind them without recourse to the legal authorities and consulting and co-ordinating with Arab nations," a statement carried by the official news agency SPA said.
"These elements should bear the responsibility for their irresponsible actions and they alone should end the crisis they have created."
Israel struck Beirut airport and military airbases and blockaded Lebanese ports on Thursday, intensifying reprisals that have killed 55 civilians in Lebanon since Hezbollah captured two Israeli soldiers a day earlier.
"They [the elements] are exposing Arab nations and their gains to grave dangers without these nations having a say in the matter," said the statement, which reiterated Saudi support for Palestinian and Lebanese resistance against Israeli occupation.

The statement did not make clear what it meant by the gains of Arab nations.
Criticism of some Arab resistance movements, which act without consulting any Arab government, have been the focus of some Saudi press coverage lately.
