Iran warned the United States would bear “full responsibility” in case of a retaliatory attack by Israel on the Islamic Republic after US President Joe Biden indicated he was aware of Israeli plans to do so, AFP reports.

Amir Saeid Iravani, Iran’s ambassador to the United Nations, called Biden’s remarks “profoundly alarming and provocative” in a letter addressed to United Nations chief Antonio Guterres and the Swiss presidency of the UN Security Council.

“This inflammatory statement (of Biden) is deeply concerning, as it indicates the United States’ tacit approval and explicit support for Israel’s unlawful military aggression against Iran,” Iravani wrote in the letter.

“Therefore, the United States will bear full responsibility for its role in instigating, inciting and enabling any acts of aggression by Israel against the Islamic Republic of Iran, in flagrant violation of the fundamental principles of international law and the United Nations Charter,” he said.
