The truce that will allow humanitarian aid in the war-torn country is expected to begin at 8:00 p.m. on Tuesday.
"Any military violation of the ceasefire from al Qaeda and those who stand with it and support it and fund it will be responded to by the army and security and the popular committees," Colonel Sharaf Luqman said in a statement broadcast by Yemen's Saba news agency.
The coalition also targeted the residence of Yemen's former president Ali Abdullah Saleh, according to witness accounts.
Yemen has been engulfed in violence and political deadlock since late 2014. The Saudi-led air campaign was launched at the request of President Hadi, who fled the country amid hostilities after the Houthis took control of large areas of the country, including Sanaa.
According to UN estimates, almost 650 civilians have been killed and 1,300 others injured in Yemen since the beginning of the Saudi-led airstrikes, while over 300,000 Yemenis have been displaced amid violence.
