Al-Alam Arabic language news network on Sunday cited Yemen Press as reporting that the fighter jets of the Saudi-led coalition have dropped weird bombs, believed to contain poisonous gas, on parts of Yemen.

According to the report, the warplanes dropped parachute bombs on parts of Sa'dah province in northwestern Yemen.

The bombs belched black smoke when falling down, it said.

On March 26, Saudi Arabia and some of its Arab allies began to militarily interfere in Yemen's internal affairs by launching deadly air strikes against the Houthi Ansarullah movement in an attempt to restore power to fugitive Yemeni President Abd Rabbuh Mansur Hadi, a close ally of Riyadh.

The Saudi-led coalition, including military forces from Qatar, the United Arab Emirates (UAE), Kuwait, Egypt, Sudan, Bahrain, Morocco, Jordan, and Egypt, has killed hundreds of civilians so far.
