Saudi Arabia said it intercepted and shot down a Scud missile fired by Yemen's Houthi rebels into its territory, the second such incident since the monarchy launched airstrikes against the Iran-backed rebels five months ago.
The official Saudi Press news agency SPA reported Wednesday that the kingdom's air defence destroyed the Scud at the Saudi border town of Jizan as well as a missile launch pad inside Yemen.
The pro-Houthi al-Masirah TV said that Yemeni military troops had fired the missile into southern Saudi Arabia, but didn't give other details.
Several Saudi security personnel have been killed in cross-border attacks by the mostly Shiite rebels since Saudi Arabia began a Sunni military intervention in Yemen in late March.
Earlier Wednesday, Saudi-owned al-Arabiya television reported that Saudi troops had pushed several kilometers inside the Houthis' stronghold of Saada near the border with Saudi Arabia.
But a spokesman for the coalition, Ahmed Asiri, downplayed the action.
"It is a tactical move, which implies no territorial ambitions," he said. "This work has been going on since the start of operations."
He said that Wednesday's action was aimed at preventing the Houthis and their allies from taking positions near the Saudi border.
Meanwhile, journalists based in Saada said that allied warplanes mounted a series of strikes in the province, from which the Houthis hail.
An exchange of shelling is raging between Saudi forces and the Houthis on the border, they reported without giving casualties.
The Houthis have seized large parts of Yemen, including the capital Sana'a, in recent months in a power struggle against Saudi-backed President Abd Rabu Mansour Hadi.
Last month, Saudi-backed militias loyal to Hadi regained control of the southern Yemeni city of Aden, in the biggest setback for the rebels.
The pro-government forces have since regained ground from the rebels in southern and central Yemen.
