Pakistani authorities said on Sunday that they had notified the United States that Pakistan was against any attack on Iran, as such an act would be "destructive for the regional peace".
A senior official in the Pakistani Foreign Ministry told The Nation outlet that "the US claims Iran is intensifying tension".
At the same time, according to another official, Pakistan has contacted Iran as well, urging it to restraint to ensure peace.
Later on, US National Security Adviser John Bolton announced that the US was deploying the USS Abraham Lincoln Carrier Strike Group and a bomber task force near Iran in a move to send "a clear and unmistakable message to the Iranian regime that any attack on US interests or on those of our allies will be met with unrelenting force".
Responding to the claims, Tehran said that it posed no threat to the US, adding that Washington's allegations were based on "fake intelligence". According to Iran's Supreme National Security Council spokesman Keivan Khosravi, Bolton's statement was "a clumsy use of an out-of-date event for psychological warfare".
