On 25 March, Gulf Air, the Bahraini flag carrier airline announced the immediate suspension of service to Sanaʽa. Somali airlines such as Daallo Airlines and Jubba Airways also encountered difficulties, as they were unable to fly over Yemen after its airspace became restricted. On 15 April, Turkish Airlines suspended all Yemen flights until 1 June. Following Hadi's request, the administration of the Egypt-based Nilesat and Saudi-based Arabsat, two satellite communication companies, stopped broadcasting Yemeni state-run television channels that had fallen under Houthi control. The channels included Al-Yemen, Al-Eman, Saba News Agency and Aden TV. Armed Houthis closed down the Sanaʽa offices of four media outlets, including Al Jazeera, Yemen Shabab and Suhail channels, as well as Al-Masdar's newspaper and website. Al-Saeeda channel was also stormed, but was allowed to remain open on the condition it not broadcast anti-Houthi material. Houthi Political Office member Mohammad Al-Bukhaiti said the channels were closed for supporting the coalition. King Salman replaced his half-brother Muqrin as crown prince with Muhammad bin Nayef and named his son Mohammed bin Salman as defence minister, and then-Ambassador to the United States Adel al-Jubeir as foreign minister. Some reports linked the cabinet reshuffle to the war. At least one political analyst suggested that Muqrin was not supportive of the military intervention, and that this cost him his position. Prince Muqrin's Yemeni Lineage was pointed out as another possible cause. The exiled Yemeni government sent a request to the UN, asking for foreign troops on the ground. On 19 June, WikiLeaks announced the intention of releasing over 500,000 Saudi diplomatic documents to the internet. In its statement, WikiLeaks referred to a recent electronic attack on the Saudi Foreign Ministry by a group calling itself the Yemen Cyber Army, but did not indicate whether they passed the documents to WikiLeaks. On 15 May 2015, new UN envoy to Yemen Ismail Ould Cheikh Ahmed proposed peace talks in Geneva. Rebel spokesman Hamed al-Bokheiti said the Houthis were willing to hold talks in any "neutral" country. Five days later the Secretary-General of the United Nations, Ban Ki-moon announced that peace talks would be held in Geneva starting on 28 May and urged all parties to participate. Houthi rebels reiterated their support for the talks while exiled government officials said they would participate only if the Houthi's withdrew from occupied cities.
