Sana'a International Airport resumed on Sunday its flights after a brief disruption resulted from threats, siege, and an attack carried out by gunmen believed to be loyal to the former President Ali Abdullah Saleh and his half brother in protest over the President Abdu Rabu Mansour Hadi's decrees.The head of General Authority for Civil Aviation and Meteorology, Hamid Faraj, said that the airport resumed on Sunday its operations and that all flights are going smoothly after one day suspension of all flights, the official Saba news agency reported.Saba quoted Faraj as saying that the airport suspended all flights on Saturday because the Traffic Control Tower of the airport had received threats from armed groups. These groups positioned in Al-Ara area, nearby the airport, opened a barrage of fire from their machine guns and rifles on the airport tower.These groups, comprised of armed tribesmen and soldiers in uniform, were seen on top of military pickups amounted with machine guns.Farag, however, denied media reports claiming that tanks had been deployed in the airport runway, saying such reports are groundless. He stressed that the airport was only closed because of threats by armed groups to take down any airplane.On Friday, Hadi issued Republican decrees whereby many high-ranking officials of Saleh's relatives and aides were dismissed and given in return administrative posts of little importance.Among the officials sacked was Mohammed Saleh al-Ahmar, the commander of the Air Force, Tariq Mohammed Abdullah Saleh, Saleh's nephew and the head of the Presidential Guard.US, EU, GCC states, China, Russia, and the other members of the international community showed their complete support for Hadi's decrees as they represent the first step towards implementing the second phase of the GCC-deal in which shaking up the army, and holding a national dialogue are the main terms.
