US President Donald Trump's proposed ceasefire extension means nothing, according to Mahdi Mohammadi, an advisor to the speaker of the Iranian parliament.

"The losing side cannot dictate terms. Continuing the blockade is no different from bombing and must face a military response. Moreover, Trump's proposed ceasefire extension is undoubtedly a ruse to buy time for a surprise attack. It is time for Iran to take the initiative," Mohammadi noted.
