Lebanon's prime minister and Yemen's president reported to be under house arrest in Saudi Arabia

Hariri

Saad al-Hariri, who quit as Lebanese Prime Minister in a weekend broadcast from Saudi Arabia, has been held under house arrest in the kingdom, a pro-Hezbollah daily said on Tuesday citing unnamed sources.  If true he is not the only one, also the Yemeni president Abed Rabbu Mansour Hadi is against his wish kept in Riaydh.
Lebanese newspaper al-Akhbar, which is aligned with the Shi‘ite militant group and political movement Hezbollah, said Hariri “was placed under house arrest hours after arriving in Riyadh last Friday” and had remained in detention since. Aides to Hariri, Lebanon’s most influential Sunni politician and a close Saudi ally, have denied claims that he was detained. Speculation in Lebanon over Hariri’s status continued, though, even after Saudi media showed him meeting with King Salman and reported him leaving for the UAE.
Hariri's abdication declaration came as Saudi Arabia undertook an anti-corruption purge in which royals, ministers and investors have been arrested as the putative next king tightens his grip on power.In a dramatic escalation of the crisis, Saudi Arabia accused Lebanon on Monday of declaring war because of aggression by Hezbollah. Hezbollah leader Sayyed Hassan Nasrallah accused Riyadh last week of forcing Hariri to step down, and said there were “legitimate questions” over whether he had been detained.

Abed Rabbo Mansour Hadi

If Hariri really is prohibited to return to Beirut, he is not alone in being kept agianst his wish in the Saudi kingdom.They have barred Yemen's president, Abd-Rabbu Mansour Hadi, along with his sons, ministers and military officials, from returning home for months, Yemeni officials told The Associated Press.
The officials said the ban was prompted by enmity between Hadi and the United Arab Emirates, which is part of the Saudi-led coalition against Houthi rebels and has come to dominate southern Yemen, the portion of the country not under rebel control.
Hadi and much of his government have been in the Saudi capital Riyadh for most of the war.
Saudi Arabia and the UAE are the two main pillars of the coalition, which is ostensibly defending Hadi's government and is battling the Shia rebels, known as Houthis.
Hadi's inability to get back to southern Yemen underscores the president's loss of authority - even in the south that is nominally under his administration. Since Hadi left Yemen in February, he has repeatedly sent written requests to Saudi King Salman asking to return. None were processed, said a Yemeni security commander. In August, Hadi even went to Riyadh airport, planning to return to his temporary capital, Aden, in southern Yemen - but he was turned back from the airport, the commander said.
Two other Yemeni officials confirmed that Hadi, his sons and several ministers with him in Riyadh have been prevented from going to Yemen. They spoke on condition of anonymity because they were not authorised to discuss the situation."The Saudis have imposed a form of house arrest on them," the commander said. "When Hadi asks to go, they respond it's not safe for him to return as there are plotters who want to take his life and Saudis fear for his life."
Hadi's weakening has gone hand-in-hand with the UAE's growing power in southern Yemen.
The Gulf nation has trained, financed and armed militias in Yemen that only answer to it, set up prisons, and created a security establishment parallel to Hadi's government.
An AP investigation in the summer documented 18 secret prisons run by the UAE or its allies, where former prisoners said torture was widespread. The UAE denied the allegations and says all security forces are under Hadi's authority.
The Emiratis distrust Hadi, accusing him of corruption and opposing his alliance with the Islah Party, Yemen's branch of the Muslim Brotherhood, according to the three officials and a politician close to Hadi.
In an attempt to move against UAE, Hadi held a meeting on November 2 to discuss a cabinet reshuffle to push out Emirati-backed members, but so far there have been no results from the meeting. The commander said Hadi is reluctant to defy Saudi Arabia because he "doesn't want to lose the Saudis".
