Egypt has praised the prisoner swap agreement signed between the Yemeni government and the Houthi rebel group during talk held in Geneva, a statement by the foreign ministry said on Monday. Yemen's warring parties have agreed to exchange some 1,000 prisoners, including 19 Saudi soldiers, at United Nations-sponsored talks as part of trust-building steps aimed at reviving a stalled peace process, sources told Reuters on Sunday. Egypt urged the immediate implementation of the agreement, and by extension the release of all prisoners and detainees in line with the 2018 Stockholm agreement. Yemen has been mired in conflict since the Iran-aligned Houthi group ousted the government of President Abd Rabbu Mansour Hadi from the capital Sanaa in late 2014. A Saudi-led military coalition in 2015 intervened in a bid to restore the government. The United Nations says Yemen is home to the world's biggest humanitarian crisis.
