350,000 people displaced in Yemen in 2019: UN
"In 2019 alone, nearly 350,000 people have been displaced," the IOM Yemen tweeted.
A network of IOM staffers "cover over 42,000 locations to help understand the needs, numbers, locations and conditions populations in Yemen, including displaced people, returnees and migrants," the tweet said.
Yemen has remained wracked by violence since 2014, when the Iran-aligned Houthi group overran much of the country, including the capital Sanaa.
The conflict escalated the following year when Saudi Arabia and its Arab allies launched a massive air campaign aimed at rolling back Houthi gains in Yemen and supporting the country's pro-Saudi government.
More than 70,000 people have been killed in the raging conflict since 2016, according to UN estimates.
