In the early hours of Monday, the warplanes carried out as many as 25 back-to-back airstrikes against various districts of the Yemeni capital, Sana’a, local media said, Press TV reported.
Taking the brunt of the attacks was the capital’s Wadi Sar District, which was struck 13 times.
There have been no immediate reports of possible casualties.
The assaults also hit Bani Matar District, the presidential palace and the capital’s As Sabain Square, leaving two civilians dead.
Sabin Square came under attack hours after the leader of Yemen’s Houthi Ansarullah movement, Abdul-Malik Badreddin al-Houthi, delivered a speech to a large crowd of Yemenis there marking the birth anniversary of Prophet Muhammad (PBUH).
A day earlier, the jets had targeted the city of Sa’ada in northwestern Yemen six times, killing four civilians and injuring a number of others.
Riyadh’s attacks have killed at least 11,400 people in the kingdom’s impoverished neighbor since March 2015, according to the latest tally by a Yemeni monitoring group.
The Saudi campaign was launched with the aim of reinstating Yemen’s fugitive former president Abd Rabbuh Mansour Hadi.
Hadi, a dedicated Riyadh ally, resigned last year, ignoring calls to reverse the decision and fled to the Saudi capital.
He recently returned to the country’s port city of Aden, but has rejected a United Nations peace roadmap, saying the initiative favors the Houthi Ansarullah movement, which have been defending the country against the Saudi invasion.
