TEHRAN: Israel's threat of military action against Iran's alleged nuclear weapons programme is not a bluff, the country's deputy foreign minister said. "The one who's bluffing is Iran, which is trying to play with cards they don't have," Danny Ayalon told Sky News. "All the bravado that we see and the testing and the very dangerous and harsh rhetoric is hiding a lot of weaknesses." Ayalon also accused Iran of stalling tactics. "If Iranian behaviour and conduct continues as they have exhibited so far, it is obvious that their intentions are only to buy time and procrastinate."
