"Resorting to military acts against Yemen which is entangled in an internal crisis and fighting terrorism will further complicate the situation, spread the range of crisis and destroy opportunities to settle the internal differences in Yemen peacefully," Foreign Ministry Spokeswoman Marziyeh Afkham said on Thursday.
She underlined the necessity for implementing national agreements among the Yemeni groups and parties as soon as possible, and called for an immediate halt to air strikes and military acts against the Yemeni people and the country.
Afkham expressed concern about the spread of extremism and strengthening terrorism, and said, "This aggression will merely result in the spread of terrorism and extremism and will spread insecurity to the entire region."
Saudi Arabia launched airstrikes against Yemen early Thursday, one day after the US-backed Yemeni president fled the country.
US President Barack Obama authorized the provision of logistical and intelligence support to the military operations, National Security Council Spokesperson Bernadette Meehan said late Wednesday night.
She added that while US forces were not taking direct military action in Yemen, Washington was establishing a Joint Planning Cell with Saudi Arabia to coordinate US military and intelligence support.
At least 25 Yemeni civilians, including children, were killed and tens of other wounded in the today morning Saudi air strike.
