Tens of thousands of Yemenis staged large demonstrations in the country's temporary capital of Aden and across the government-controlled provinces, to show support for the president, residents told Xinhua.

High-ranking government and military officials, attended the protests that aimed to show support for Yemen's President, Abdu-Rabbu Mansour Hadi, against the Shiite Houthi group.

Aden's governor, Maj. Gen. Aidarous Zubaidi, along with other governors, arrived at the Public Square in Aden's neighbourhood of Khormaksar, to declare their full support for Hadi.

The protesters raised slogans that denounced a UN road map, prepared to end the 19-month of military conflict in the impoverished Arab country.

"No for legitimising the Houthi coup" and "The United Nations reward Houthi putschists," read the banners, carried by the demonstrators in Aden.

One of the protest organisers told Xinhua that "thousands of people went out on the streets in Aden and elsewhere in southern Yemen, to illustrate their disapproval of the UN envoy's plan."

Last Saturday, President Hadi announced his rejection of the UN envoy's peace plan, saying, its contents "bare seeds of war in the country."

The UN road map called for naming a new vice president, after the withdrawal of the Shiite Houthi rebels from the capital Sanaa and other northern provinces and handing over all heavy weapons to a third party.

The UN plan also suggested forming a new government, that will be formed from the two-warring sides and would not be led by President Hadi, who would transfer his power to the new vice president.

The situation in Yemen has deteriorated economically and politically since Mar, 2015, when war broke out between the Shiite Houthi group, supported by former President, Ali Abdullash Saleh, and the government, backed by a Saudi-led Arab coalition.

Houthis and Saleh's forces hold most of Yemen's northern regions, while government forces, backed by Saudi-led military coalition, share control of the rest of the country, including seven southern provinces.

The civil war, ground battles and air strikes have already killed more than 10,000 people, half of them civilians, injured more than 35,000 others and displaced over two million people, according to humanitarian agencies.
