The Yemeni Shia Houthis are planning to launch attacks at 300 critical infrastructure facilities in Saudi Arabia and the United Arab Emirates (UAE), SABA News Agency reported.
According to the agency, the Houthis will attack 299 more targets, including military and strategic facilities in Saudi Arabia and the UAE.
This comes after Houthis claimed responsibility for drone attacks on Saudi oil facilities last week, calling it the "largest military operation" conducted by militants since the start of the armed conflict in 2015.
The attack caused a fire and some minor damage to one of the pumps of Saudi Aramco's cross-country pipelines. The company has stated that it has halted crude oil traffic via the pipeline as a precautionary measure.
In retaliation, the Saudi-led coalition launched airstrikes in war-torn Yemen on Thursday in which at least six people lost their lives while several others, including two Russian women, were wounded.
The coalition warplanes which hit the residential area at the intersection of Rabat and Rakas streets in Sanaa were being controlled by the Houthis, Sputnik reported.
The air strikes came after the Houthis claimed responsibility for drone attacks on Saudi oil installations on Tuesday.
Yemen has been engulfed in a civil war since 2015. Yemeni Abd Rabbuh Mansur Hadi's government, backed by Saudi-led coalition, is in violent conflict with Houthi forces loyal to former President Ali Abdullah Saleh.
