United Nations, April 24 (RHC)-- United Nations Secretary General Antonio Guterres has strongly condemned Saudi Arabia's deadly attack on a wedding ceremony in Yemen's Hajjah province. 

On Sunday, a wedding ceremony in Yemen's was targeted by Saudi airstrikes in which nearly 50 people were killed and 55 others injured.  Saudi jets also carried out raids on ambulances transporting the casualties to local hospitals.

"The Secretary General reminds all parties of their obligations under international humanitarian law concerning the protection of civilians and civilian infrastructure during armed conflicts. He calls for a prompt, effective and transparent investigation," said UN spokesman Stephane Dujarric said in a statement released on Monday. 
 
Iran's Foreign Ministry spokesman Bahram Qassemi also slammed the attack as a violent and inhumane move by the Saudis.  He added that Saudi Arabia's recent increase on attacks on innocent civilians is a sign that they have been unsuccessful in obtaining their goals in the war-torn country.  

While offering condolences to the families of the victims, Qassemi said that "the increase of bombing raids on residential areas is a sign of frustration and failure of those attacking Yemen," he added.
