Iranian President Masoud Pezeshkian spoke to Pakistan's Prime Minister Shehbaz Sharif after the US seized an Iranian-flagged cargo ship in the Strait of Hormuz, amid worsening tensions between Iran and the US.
Pezeshkian accused the US of 'bullying behaviour' and 'unreasonable actions', leading to increased suspicion that the US will 'betray diplomacy', according to Iranian state media.
Pakistan has positioned itself as a mediator to calm the flaring tensions between the US and Iran, despite talks in Islamabad collapsing without a deal on April 12.
The US Navy fired upon and boarded the Iranian-flagged cargo ship, Touska, in the Gulf of Oman, with the vessel now under US Marines custody.
US President Donald Trump said the ship was nearly 900 feet long and weighed almost as much as an aircraft carrier, and that it was seized due to US Treasury sanctions.
The Iranian military has vowed retaliation against the US military, with a spokesperson warning of an 'armed response'.
Pakistan's military and civilian politicians have made efforts to push for a second round of talks between the US and Iran, with Pakistan's army chief heading to Tehran to carry US proposals.
