The Saudi-led coalition intensified its airstrikes in Yemen's capital Sanaa and the province of Jawf in the past 24 hours.
In Sanaa, airstrikes resumed this morning targeting the Al-Nahdain brigades within the presidential palace and the missile brigades in the west after heavy overnight raids.
Also, eyewitnesses said airstrikes targeted the military camps around the TV station.
There were no reports of casualties.
In Jawf, the Saba news agency said the coalition carried out 45 air raids since last night. Houses and properties of people were damaged and destroyed in the raids, it said.
Moreover, the coalition, which has been bombing Yemen since March, carried out fresh airstrikes in the provinces of Marib and Baidha, locals said.
Meanwhile, the battles between the pro-government and Houthi forces continued in Sanaa, Jawf, Dhali and Taiz.
The escalation comes amid desperate efforts to launch a new round of peace talks in order to end the ten-months conflict.
News reports quoted government officials as saying the UN envoy Ismail Ould Cheikh Ahmed had failed to convince the Houthi militants to attend talks.
The factions failed to hold talks by mid-January as it was scheduled following their talks in Swiss last month.
Ahmed ended a visit to Sanaa two days ago. On the visit, he held talks with factions including the Houthi group and the General People's Congress.
