A soldier was killed Sunday in a clash with Houthi rebels, according to the country's official news agency.

The SPA news agency said Muhammad Suud Farac al-Belevi was killed in the clash along Saudi Arabia's southern border with Yemen.

Yemen has been wracked by chaos since late 2014 when the Houthis and their allies overran the capital, Sanaa, and other parts of the country.

The conflict escalated in mid-2015 when Saudi Arabia and its Arab allies launched a major air campaign aimed at reversing Houthi military gains and shoring up Yemen's embattled Saudi-backed government.

Two rounds of UN-backed peace talks have failed to resolve the conflict in which thousands of Yemenis are believed to have been killed and an estimated 2.5 million forced to flee their homes.
