Yemen's Houthis say attacked two Saudi oil tankers

Saudi Arabia expects imminent co-ordinated attacks from Iraqi militias north of the Persian Gulf state and from Yemen's Houthis from the south under the supervision of Iran's Islamic Revolutionary Guard Corps, a senior Saudi official said.

An attack by Yemeni Houthi rebels late Thursday wounded 11 civilians in southern Saudi Arabia, the Riyadh-led coalition said, an unprecedented toll in the kingdom in over four years of hostilities.

Yemen's Houthis say they launched drones and ballistic missiles in Marib and Hadramout.

The Iran-backed militia said they had targeted the armed forces in two resource-rich provinces, as escalating violence in Yemen imperils a fragile truce.

Houthi rebel attacks in Yemen have killed at least 30 government forces and wounded at least 50 others, according to government officials

These were the eighth and ninth Saudi oil tankers targeted since the start of the blockade last month, according to figures given by a Houthi military spokesman
