Local sources told Arabic-language al-Masirah television network that the civilians lost their lives as Saudi warplanes struck two houses in the al-Marawi'ah district of the province, located 150 kilometers southwest of the capital, Sana'a, on Saturday evening.

The development came shortly after Saudi military aircraft struck a number of telecommunications towers in the area.

Separately, Saudi jets pounded a house in the al-Khawkhah district of the same Yemeni province, leaving a woman and a girl dead. Two people sustained injuries in the aerial attack, Press TV reported.

Saudi fighter jets also launched four airstrikes against an area in the Dhubab district of the southwestern Yemeni province of Ta'izz, though no reports of possible casualties were immediately available.

Additionally, a boy was seriously wounded in a blast of a Saudi cluster bomb in the Bani Sa'd area of the al-Dhahir district, which lies in Yemen’s northwestern province of Sa’ada.

Elsewhere in the As Silw district of Ta’izz Province, a girl and a boy were killed as pro-Saudi militiamen loyal to resigned Yemeni President Abd Rabbuh Mansur Hadi opened fire.

Saudi Arabia has been engaged in a deadly campaign against Yemen since March 2015 in an attempt to bring back the former Yemeni government to power and undermine the Houthi Ansarullah movement.

The impoverished Arab country is grappling with the scarcity of food supplies and outbreak of diseases amid Saudi Arabia’s atrocious airstrikes.

The United Nations International Children's Fund (UNICEF) says 7.4 million Yemeni children are in dire need of medical help, and 370,000 run the risk of severe acute malnutrition.
