Saudi Arabia’s war machine is using every last minute for more attacks against Yemenis before a UN - brokered ceasefire takes effect. Saudi fighter jets carried out dozens of airstrikes across Yemen on Sunday, targeting civilians’ houses and properties, Yemen's official Saba Net news agency reported. Saudi warplanes conducted a dozen airstrikes on the Sirwah district of the central province of Ma'rib. They also carried out nine air raids against the Matun district in the northern province of Jawf and launched another attack on the Karsh district of the southwestern province of Lahij. Separately, Saudi jets conducted over 12 airstrikes against the Nihm district of the western province of Sana'a. There were no immediate reports of possible casualties and the extent of damage inflicted by the Sunday attacks. On Saturday, Saudi jets launched an aerial assault against the Dhubab district of the southwestern province of Ta’izz, leaving five people dead, including three women and a child. Reports coming out of Yemen say Saudi Arabia is increasing its military forces in Yemen's Hajjah province ahead of the UN-mediated ceasefire that comes into effect on Sunday midnight. Scores of Saudi troops and some forces loyal to Yemen’s former president Abd Rabbuh Mansur Hadi were also deployed to Nihm, near the capital Sana’a. The deployment is reportedly aimed at launching a military operation to seize the control of the capital if the upcoming talks fail to end the conflict. The truce was announced by the UN special envoy for Yemen Ismail Ould Cheikh Ahmed as a step to calm the situation ahead of the negotiations scheduled to be held on April 18 in Kuwait. Saudi Arabia has been waging a war on Yemen since late March 2015 in a bid to return Hadi to power and undermine the Houthi Ansarullah movement. Nearly 9,400 Yemenis, including 4,000 women and children, have lost their lives in the deadly military campaign. Yemenis, in return, have been carrying out retaliatory attacks on the Saudi forces deployed in the country as well as targets inside Saudi Arabia.
