Yemeni rebels and their allies have killed more than 370 civilians in Saudi border regions since a Saudi-led military operation began against the rebels last March, the coalition said Tuesday.
Its spokesman Brigadier General Ahmed al-Assiri told AFP the civilian death toll was now 376.
He also said that more than 40,000 mortar bombs, Katyusha rockets and other projectiles have been fired into the kingdom from Yemen since the Arab coalition began its campaign to push the rebels from seized territory in the neighbouring country.
That is an average of more than 129 projectiles per day.
They were fired by the Iran-backed Houthi rebels and their allies, elite troops loyal to former president Ali Abdullah Saleh, Assiri said.
"Twelve Scud missiles were intercepted," he added.
