Supreme leader Al Houthi spoke live Thursday night in Yemen on al-Masirah TV, saying, "If any army tries to invade our country, we will prove that Yemen will be a grave for those who invade us."
Iran denounced the military intervention. Marzieh Afkham, a spokeswoman for the country's Foreign Ministry, said the operation will throw an already complicated situation into further turmoil and disrupt chances at a peaceful resolution to Yemen's months-long internal strife. It also won't help a region already facing terrorist threats from groups like ISIS and al Qaeda, she said.
