Q: BEIRUT (Reuters) - Lebanon believes  Saad al-Hariri  is held in Saudi Arabia  from where  he  resigned as prime minister  two top Lebanese government officials said  amid a deepening crisis pushing Lebanon onto the frontlines of a power struggle between Saudi Arabia and Iran.

In a televised statement indicating deep concern at  Hariri âs situation   his  Future Movement political party said  his  return home was necessary to uphold the Lebanese system  describing  him  as prime minister and a national leader.
 Hariri âs shock resignation  read out on television from Saudi Arabia  came as a shock even to  his  aides and embroils Lebanon further in a regional contest between Riyadh and Tehran.
 Hariri âs exit fueled wide speculation that the Sunni Muslim politician  long an ally of Riyadh  was coerced into stepping down by Saudi Arabia as it seeks to hit back against Iran and its Lebanese Shiâite ally Hezbollah.
In his resignation speech   Hariri  denounced Iran and Hezbollah for sowing strife in Arab states and said  he  feared assassination.  His  father  a veteran former prime minister  was killed by a bomb in 2005.
âKeeping  Hariri  with restricted freedom in Riyadh is an attack on Lebanese sovereignty. Our dignity is his dignity. We will work with (foreign) states to return him to Beirut â said the senior Lebanese official  speaking on condition of anonymity because the government had yet to declare this position.
Saudi Arabia says  Hariri  resigned because Hezbollah  which was included in  Hariri âs coalition government  had âhijackedâ Lebanonâs political system.
 Hariri  aides had until Thursday denied  he  was under house arrest but took a dramatically different tone after a meeting of the Future Movement convened at Haririâs Beirut residence on Thursday.
 Hariri âs aunt  Bahia  sat next to Siniora as he read the statement. The party stood behind his leadership  it said.
 Hariri  came to office last year in a political deal that made the Hezbollah-allied Christian politician Michel Aoun head of state and produced a coalition government grouping most Lebanese parties including Hezbollah.
Saudi Arabia blessed the government at the time  but has been fiercely critical of the Hariri-led government since  he  stepped down  saying it failed to act against Hezbollah  whose guerrilla army is far more powerful than the weak state.

Saudi Arabia had wanted  Hariri  to take a tougher stance toward Hezbollah  and  he  failed to do so  the fourth source said. â He  was functioning as if it is business as usual  so the Saudis had to accelerate the process and to force a resignation.â
 Hariri  flew to Saudi Arabia last Friday.
The top Lebanese government official  speaking on condition of anonymity  said: âLebanon is heading toward asking foreign and Arab states to put pressure on Saudi Arabia to release Prime Minister Saad al-Hariri.â

Q: Senate Intelligence Committee Chairman Richard Burr (R-S.C.)  said "we have not come to any final conclusions" about the Russia investigation on Oct. 4  but that they are still looking into the Mayflower meeting  former president Barack Obama's response to Russian hacking  the Intelligence Community Assessment and the drafting of the RNC's platform.

Senate Intelligence Committee Chairman Richard Burr (R-S.C.)  said "we have not come to any final conclusions" about the Russia investigation on Oct. 4  but that they are still looking into the Mayflower meeting  former president Barack Obama's response to Russian hacking  the Intelligence Community Assessment and the drafting of the RNC's platform. (Reuters)
âThere is consensus among members and staff that we trust the conclusions of the ICA â Sen. Richard Burr (R-N.C.)  the committeeâs chairman  said at Wednesday news conference  referring to the intelligence communityâs assessment that Russia was behind hackings of the Democratic National Committee and Hillary Clinton campaign director John Podestaâs email account and had attempted to exploit public opinion by sowing false information  much of it through fake social media accounts.
âBut we donât close our consideration of it â  he  added.
 Burr  also said that âthe issue of collusion is still openâ and would not be resolved until the committeeâs work was done.  He  said that a deadline for the committee was the looming start of the 2018 primary season.
âWeâve got to make our facts  as it related to Russiaâs involvement in our election  before the primaries getting started in 2018 â  Burr  said.

 Burr  and Sen. Mark R. Warner (D-Va.)  the committeeâs vice chairman  said the committee has interviewed more than 100 people and reviewed more than 100 000 documents  many of them from the intelligence community  President Trumpâs inner circle and former members of the Obama administration. In some areas of the investigation   Burr  added  investigators had âexhausted every individualâ they could speak with in several areas of the probe â such as an April 2016 meeting at the Mayflower Hotel in Washington.
 Burr  said the committee had interviewed seven people about that meeting and that âthe testimony of all seven were consistent.â
 He  said the committee had also âinterviewed every personâ that was involved in drafting the Republican campaign platform  suggesting that investigators had found no evidence of nefarious activity by Trump campaign officials in fashioning that platform to support a âstrong ally in Ukraine  but also leave the door open for better relations with Russia.â
 Burr  also told reporters that the committee had âhit a wallâ in attempting to verify the details of a salacious dossier about Trumpâs alleged exploits in Russia  mostly because its author  former British spy Christopher Steele  had rebuffed the committeeâs efforts to speak with him about his sources and about who paid for the compilation of the report.
âI can compel you to come â  Burr  said  as a warning to any potential witnesses who might not want to comply with the committeeâs investigation. But  Burr  later said that  he  had no such leverage over Steele  a British citizen  and could only threaten that the committeeâs report âwonât be flatteringâ as it relates to  him  if  he  refuses to cooperate.
The committee has also scheduled an additional 25 interviews for this month   Burr  added. Google executives  who have also been invited to testify publicly before the committee on Nov. 1  are expected to be among those asked to attend the closed-door interviews that have been scheduled in October.

 Burr  added that the committee would not release the content of those ads  though  he  added that the committee would be âfineâ with any of the social media companies choosing to release the content of documents and other information they had turned over to the committee themselves.
