Warplanes from a Saudi-led coalition launched air strikes on June 1 against Yemen's Iranian-backed Huthi rebels in northern, central, and southern parts of the country.
The air strikes in the north were accompanied by cross-border artillery fire from Saudi Arabia on Shi’ite Huthi militants’ strongholds in northern Yemen’s Sa’ada Province.
Those attacks followed fighting during the previous 48 hours along the Saudi-Yemeni border -- including a barrage of about 20 rockets fired by Huthi rebels in Sa’ada Province on May 30 at the southwestern Saudi border city of Najran.
The Saudi-led coalition began air strikes in Yemen in March in a bid to restore Yemeni President Abd-Rabbu Mansur Hadi to power.
Hadi, who is in exile in Saudi Arabia, fled the capital in March after Huthi rebels pushed their way into central and south Yemen.
The latest violence comes amid unconfirmed reports that U.S. diplomats have launched talks in Oman with representatives of the Huthi rebels.
