A Saudi airstrike targeted a Pakistani boat off the Yemeni coast on Sunday, killing at least six sailors.

Saudi Arabia’s air raid targeted the boat, which was carrying 12 Pakistani sailors off Mukha coast in the Yemeni province of Ta’izz, Yemeni Saba news agency reported.

The other six sailors are still unaccounted for, according to the report.

The Saudi deadly attack comes as the regime continues its brutal military invasion on neighboring Yemen, which was launched more than a year ago to reinstall the former Yemeni government.

Abd Rabbuh Mansour Hadi, Yemen’s former president, has ordered an assault on the country’s Red Sea coast against Houthi fighters and allied army forces, who have been defending the war-torn country against deadly Saudi aggression.

According to Sunday reports, Saudi airstrikes had been intensified on the province of Ta’izz.

The province has seen heavy clashes on the ground between pro-Hadi militants and Yemeni armed forces in recent days.

Also, Saudi air raids have killed a child as the regime bombed residential buildings in the province of Sa’ada.

The girl’s father and her two brothers were also wounded in the assault, which hit the province’s district of Razih.

The Saudi military campaign against Yemen has killed over 11,000 civilians and left the country in a catastrophic situation.
