Iran�s top security official says threatening to use �other options� against Iran � the terminology commonly used to refer to military action � is an "illegal threat" to another country, giving Iran the right to resort to its own �available options� in response.

US President Joe Biden used his first meeting with new Israeli Prime Minister Naftali Bennett to threaten to �turn to other options� against Iran if diplomacy failed.

�We�re putting diplomacy first and seeing where that takes us,� Biden said ahead of the meeting, held at the White House on Friday, �If diplomacy fails, we�re ready to turn to other options.�

By diplomacy, the US president was pointing to the talks in Vienna, Austria, to reinstate the 2015 Iran nuclear agreement, which was abandoned by former US President Donald Trump in 2018.

Trump�s move was lauded by Israel at the time. Biden�s decision to rejoin the nuclear deal has been opposed by Bennett and his predecessor, Benjamin Netanyahu.
