Dozens of Houthi militants have been killed in Saudi-led airstrikes on Yemen's border cities of Saada, the stronghold of the Houthi militant group, and Hajjah, local sources in the two cities said on Wednesday.
More than one hundred others were injured and many homes destroyed in the airstrikes, the sources said, while affirming civilians were among the victims.
The airstrikes were conducted throughout night after Houthi militants shelled the Saudi Najran city on the border with Yemen early Tuesday.
Saudi interior ministry said the militants randomly shelled parts of Najran killing three civilians.
Properties were destroyed in the attack which forced Saudi authorities to suspend study and flights in Najran.
The attack on Najran was carried out after Saudi foreign minister said the Saudi-led airstrikes on the Houthi militants would be paused in order to deliver aid to desperate millions of Yemenis affected by violence.
On March 26, Arab countries launched the military operation after the Houthi militants with support from forces loyal to the former president had ousted president and government.
The countries were Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain, Egypt, Morocco, Jordan and Sudan.
In the past 24 hours, fighter jets from these countries also struck military positions and weapons depots in other Yemeni cities including Dhamar.
The strikes coincided with continued confrontations between pro-government and pro-Houthi fighters in Aden, Taiz and Dhale.
Local sources in Aden said today fierce confrontations between the popular resistance and militants have been continuing in the district of Al-Tuwahi.
Chief of the fourth military command was killed in the battles in this district lately.
Reports said a new chief has been named.
