Iran's foreign ministry said on Monday it had summoned the French ambassador to Tehran to protest what it described as "interference in Iran's internal affairs" by two diplomats who were briefly detained earlier this month.

"Yesterday, the French ambassador in Tehran was summoned to the Ministry of Foreign Affairs, where it was stressed that the French government must cease such actions and such interference in Iran's internal affairs under misleading labels," said the ministry's spokesman Esmaeil Baqaei in a weekly press briefing, adding that the diplomats had carried out activities "that were in no way justified".

Iran's foreign ministry warned on Monday of "unforeseen" consequences following Ukraine's attack on an Iranian vessel in the Caspian Sea over the weekend.

Lebanon’s army on Sunday condemned ongoing Israeli military activities in the country’s south that it said were preventing its full deployment under a framework deal reached with Israel last month.
