Iranian Ambassador to Yemen in a message expressed outrage at continued closure of Sana'a Airport, calling for open service for the flights carrying humanitarian aid to Yemen exposed to severe shortage of food and medical supplies.
"The Yemeni people are suffering a lot due to the closure of Sanaa International Airport," Hassan Irloo wrote in his Twitter account.
"Thousands of critically ill patients need to travel for treatment," he added.
"Thousands of immigrants want to return home to their own families," Irloo noted.
"When does the human conscience wake up?" Iranian diplomat asked.
Saudi Arabia and its regional allies attacked Yemen in March 2015 to bring back to power the deposed president of Yemen Abdrabbuh Mansour Hadi.
Since then, the invaders have committed horrible war crimes against Yemeni civilians.
Earlier, Iranian Foreign Minister Mohammad Javad Zarif in an online conversation with his Yemeni counterpart Hisham Sharaf said the continuation of aggression and cruel blockade by the Saudi coalition in Yemen and confiscating vessels carrying food and fuel is not acceptable.
Iran believes that the only way for establishing stability in Yemen is to preserve territorial integrity and unity among all Yemeni groups and to hold intensive political talks among different parties for establishing the united government, he added.
Yemen belongs to all Yemenis, Zarif reiterated.
