This month marks two years since a Saudi-led coalition entered the conflict in support of Hadi's government. UN efforts to broker peace and seven ceasefire deals have failed to end the fighting.
The US has carried out a new wave of airstrikes against Al-Qaeda in Yemen.
Drones fired missiles at targets linked to Al-Qaeda in the Arabian Peninsula in two separate attacks.
Residents said one missile hit a vehicle on the outskirts of the southern city of Ahwar, killing two suspected al-Qaeda members.
The group have exploited the power vacuum left after two years of war between President Hadi’s government and Shiite rebels who control the capital Sanaa.
Meanwhile, protesters gathered outside the UN office in the city, angry at how the conflict is affecting public services and contributing to a food crisis.
“We are here to tell the United Nations that it is now accused of (contributing to) the starvation of the people of Yemen. It is now responsible for the displacement of the Yemeni people. We are here for all Yemeni people, not a certain political party,” Khalil el Shamri, head of the workers syndicate of Yemen.
