TEHRAN (Press Shia) – Saudi-led coalition has stepped up attacks on Yemen and its warplanes bombed the presidential palace in Yemen’s capital and some other areas across the country on Monday.

The palace in Sana’a, currently used by the Houthi Ansarullah Movement, was pounded by at least four airstrikes late Monday, the Arabic-language al-Masirah television network reported.

It’s the first time the building has been targeted in almost three years of war.

They also targeted the al-Sabeen region near Sana’a five times.

In the meantime, at least 18 civilians were killed or injured on Monday in the Saudi-led coalition warplanes attack on Na'adh Market on Sanhan and Bani Bahlol districts in Sana'a province, the Yemen’s official Saba News Agency reported.

Saudis have stepped up attacks on Yemen, in particular Sana’a following death of their ally, the former Yemeni dictator Ali Abdullah Saleh. Saleh was killed after betraying the Yemen revolution and allying with the Saudi-led coalition which is pounding the country for the past three years.

Yemeni capital witnessed street clashes between the Houthi Ansarullah Movement and Saleh forces in recent days but the country’s Army Spokesman Brigadier General Sharaf Luqman said on Monday that security has been restored in the whole Sana’a province.

Yemen’s defenseless people have been under massive attacks by the Saudi-led coalition for the past three years but Riyadh has reached none of its objectives in Yemen so far.

Over 12,000 Yemenis, including thousands of women and children, have lost their lives in the deadly military campaign.
