TEHRAN (FNA)- Head of the Yemeni Red Crescent Society Mohammad Ahmad al-Kebab in a letter to his Iranian counterpart Seyed Amir Mohsen Ziayee thanked Iran for the recent humanitarian and medical aid cargoes sent to his country.

"I appreciate the unsparing help and relief operations as well as the humanitarian attempts of the Iran Red Crescent Society (IRCS)," al-Kebab said in his letter sent on Monday.

He expressed the hope that interactions and mutual cooperation between the two countries' red crescent societies would increase in future.

On March 31, Iran sent a cargo plane carrying humanitarian aid, including medical equipment, to Yemen.

Head of Iran Red Crescent Society (IRCS) Relief and Rescue Organization Nasser Charkhsaz told reporters that 19 tons of medicines and medical equipment was sent to Yemen.

He said the four consignments sent before included a total 50 tons of relief, medical, treatment, and consumer items.

Charkhsaz added that more humanitarian aids will be sent to Yemen if that country demands for more help.

Saudi Arabia has been striking Yemen for twelve days now to restore power to fugitive president Mansour Hadi, a close ally of Riyadh. The 12 days of the Saudi-led aggression has killed at least 887 Yemenis, including hundreds of women and children.

Hadi stepped down in January and refused to reconsider the decision despite calls by Ansarullah revolutionaries of the Houthi movement.

Despite Riyadh's claims that it is bombing the positions of the Ansarullah fighters, Saudi warplanes are flattening residential areas and civilian infrastructures.

Five Persian Gulf States -- Saudi Arabia, the United Arab Emirates (UAE), Bahrain, Qatar and Kuwait -- and Egypt that are also assisted by Israel and backed by the US declared war on Yemen in a joint statement issued on March 26.

US President Barack Obama authorized the provision of logistical and intelligence support to the military operations, National Security Council Spokesperson Bernadette Meehan said late on March 25.

She added that while US forces were not taking direct military action in Yemen, Washington was establishing a Joint Planning Cell with Saudi Arabia to coordinate US military and intelligence support.
