Credible security sources have denied reports claiming Pakistan gave Iran any nuclear assurance in case of an Israeli attack. These claims were circulated by some foreign media outlets. Officials said no such commitment was made by Pakistan.

Iran's top general, Mohsen Rezaei of the Islamic Revolutionary Guard Corps (IRGC), revealed that Pakistan has privately assured Tehran of nuclear retaliation against Israel if the Jewish state launches a nuclear attack on the Iranian capital, reported News18.

Pakistan has closed all its border crossings with neighbouring Iran for an indefinite period, provincial officials said on Monday, as Israel and Iran trade intense strikes and threaten further attacks.
