The Iranian government has been using social media to convey its stance on the ongoing conflict, with the 'key' becoming a recurring metaphor for its demands.
Iran is leveraging its control of the Strait of Hormuz, a critical oil route, to pressure the US and Israel to stop attacks on Lebanon.
A two-week temporary ceasefire was reached earlier in the week, but Israel insists its parallel war in Lebanon is not part of the truce.
Iran's officials have stated that a ceasefire in Lebanon is a key condition for reopening the Strait of Hormuz, which has seen only 12 ships pass through since the conflict began.
The 'key' metaphor emerged as a response to US President Donald Trump's ultimatum, with Iranian embassies around the world posting satirical messages on social media.
Iran's parliament speaker has warned of 'explicit costs and STRONG responses' if Israel continues to attack Hezbollah, while Netanyahu has authorized negotiations with Lebanon to disarm Hezbollah militants and establish relations.
