[Regnum] If the United States refuses to fulfill its obligations under the previously concluded memorandum on ending the conflict, Iran will take harsh retaliatory measures. This was stated by Iranian Foreign Ministry spokesman Ismail Baghaei on June 20.
"If the enemy refuses to fulfill its express obligations or obstructs their implementation, the Islamic Republic of Iran, relying on its strategic capabilities, will certainly take harsh retaliatory measures," Bagai said on the state television and radio company.
Earlier in the day, the Iranian Armed Forces Command Headquarters stated that due to the failure of both the United States and Israel to comply with the terms of the ceasefire agreement, and in particular due to Israel's continued attacks on Lebanon, the Strait of Hormuz would be closed again.
On June 15, the United States and Iran signed a memorandum ending the conflict. Negotiations on a basic agreement were expected to begin next, lasting 60 days, but these talks have not yet begun. Meanwhile, the United States lifted the blockade of Iranian ports, and traffic through the Strait of Hormuz was expected to be restored.
Iran has previously repeatedly stated that hostilities must cease throughout the region, including in Lebanon. Israeli Prime Minister Benjamin Netanyahu, meanwhile, has stated that the country will not withdraw troops from southern Lebanon. On June 19, Israel and the Lebanese Hezbollah movement reached a ceasefire agreement, but it was violated within minutes.
