Sanaa, Mar 27 (IANS): Yemen's Houthi rebels have announced a three-day unilateral ceasefire with the Saudi-led coalition, voicing their commitment to a permanent truce if the coalition ends airstrikes and withdraws forces.

"We will suspend cross-border missile and drone attacks and all military actions against Saudi Arabia for a period of three days. If Saudi Arabia would agree to end its airstrikes and blockade against Yemen, we are ready to turn this declaration into a final and permanent commitment," said Mahdi al-Mashat, President of the Houthi militia's Supreme Political Council, in a televised speech on Saturday.

"The initiative includes the suspension of all ground battles on all frontlines, including the province of Marib," al-Mashat added, on the occasion marking the entering of the Yemeni civil war into its eighth year, Xinhua news agency reported.

The Houthi political leader also proposed a deal to swap all prisoners, including the brother of Yemeni President Abd-Rabbu Mansour Hadi, with the Saudi-led coalition forces.

"We call on the UN envoy to facilitate the exchange of all prisoners," al-Mashat said.

The Houthi initiative came hours after the coalition forces launched heavy airstrikes on Houthis' vital military and economic sites in the Red Sea port city of Hodeidah and the capital Sanaa in retaliation for Houthis' cross-border missile and drone attacks against oil facilities in Saudi Arabia this week.

The Houthi militia has recently intensified attacks against Saudi Arabia after it lost several strategic districts in the oil-rich provinces of Marib and Shabwa during its fighting against the Yemeni government army in the past two months.

Yemen has been mired in a civil war since late 2014 when the Iran-backed Houthi militia seized control of several northern provinces and forced the Saudi-backed Yemeni government of Abd-Rabbu Mansour Hadi out of Sanaa.

The Saudi-led Arab coalition intervened on March 26, 2015, in the Yemeni civil war in an attempt to reinstate the Hadi government.
