At least 30 people were killed in airstrikes Wednesday on a police camp in Yemen's capital.
At least 80 others were wounded when pre-dawn raids hit a prison that is run by rebels in the military police compound in Sanaa.
The strikes were carried out by a Saudi-led coalition against the rebels — a campaign that has not let up since it began in March 2015, despite an appeal Sunday by U.N. chief Antonio Guterres for a renewed push to end the "stupid war."
On Sunday, Saudi-led strikes killed at least 26 rebel fighters at a training camp northwest of the capital. On Friday, a strike on a rebel-controlled television station in Sanaa killed four guards.
U.S. Secretary of State Rex Tillerson urged Saudi Arabia on Friday to curb its military intervention in Yemen, a country in the throes of a humanitarian crisis triggered by a two-year civil war.
Last week, Yemen's former President Ali Abdullah Saleh was killed by Iran-backed rebel Houthis — his uneasy allies-turned-foes — plunging the country into further uncertainty and violence, and prompting some of the fiercest fighting since the start of a multiparty conflict three years ago.
