HABUR  Turkey (Reuters)  - Turkish President Tayyip Erdogan  threatened on Monday to cut off the pipeline that carries oil from northern Iraq to the outside world  intensifying pressure on the Kurdish autonomous region over  its  independence referendum.
 Erdogan  spoke shortly after Prime Minister Binali Yildirim said Ankara could take punitive measures involving borders and air space against the Kurdistan Regional Government (KRG) over the referendum and would not recognize the outcome.

question:
A source close to the Vatican said that Mr Bush was the most "Catholic-minded" president since John F Kennedy , who famously played down his Catholicism . 
George W Bush and Pope Benedict XVI have held an intimate meeting in Rome as rumours mounted in Italy that the president may follow in Tony Blair 's footsteps and convert to Catholicism . 
However , George William Rutler , a New York-based priest who is close to the president , was quoted by the Washington Post earlier this year saying that Mr Bush "is not unaware of how evangelism , by comparison with Catholicism , may seem more limited both theologically and historically" . 
The usual protocol for heads-of-state is a meeting in the pope 's library in the Apostolic Palace , but a spokesman for the Vatican said Benedict wanted to reward Mr Bush for the "warmth" of his reception at the White House earlier this year . 
The two men have grown increasingly close in the past two years , and Mr Bush was overheard whispering : "What an honour , what an honour , what an honour !" 
Mr Bush appointed the Catholic judges Samuel Alito and John Roberts to the Supreme Court . 
Mr Bush belongs to a Methodist church in Texas and prays at an Episcopal church in Washington . 
However , it is thought unlikely that Mr Bush would convert until after he has left office . 
However , Mr Bush did not , as expected , kneel in prayer before the Grotto of the Madonna of Lourdes . 
Mr Bush has filled the White House with Catholic speech-writers and consultants and is also thought to have asked a Catholic priest to bless the West Wing . 
Mr Bush prayed with Benedict in the Oval Office during the Papal visit to the US in April . 
Several Italian newspapers cited Vatican sources suggesting that Mr Bush may be prepared to convert . 
One source told Il Foglio , an authoritative newspaper , that "Anything is possible , especially for a born-again Christian such as Bush ." 
Mr Bush has spoken out against gay marriage , abortion and stem cell research .
answer:
George W Bush meets Pope amid claims he might convert to Catholicism . 


question:
Kyle Enos  25   was sentenced to eight years in prison for selling drugs.
 He  traded fentanyl  a powerful opiate  for bitcoin to anonymous buyers.
 Enos  posted doses in envelopes at  his  local Post Office in South Wales.
Police released the text of  his  dark web sales pitch after  his  sentencing.
This is how  drug dealer Kyle Enos  attracted customers to  his  online opiate store  trading drugs for cryptocurrency on the dark web.
 He  traded in fentanyl  the powerful painkiller that can be 50 times as strong as heroin and which contributed to Prince's death  by offering customers supermarket-style "buy one get one free" deals in exchange for bitcoin.
Police also released footage from  Enos 's custody interviews  in which he describes how the drug operation works.
 Enos  told officers  he  did not make fentanyl himself  but ordered the substance in bulk every few weeks and sold smaller doses to individual customers.  He  used  his  local Post Office in Newport  South Wales  to ship the drug in envelopes.
They communicated anonymously over the dark web   he  said  in exchange for bitcoin. The footage does not give any sense of how much money  he  was making.
The text from  Enos 's storefront is in some ways very prosaic â  he  has a summary of delivery times  offers refunds and guarantees and emphasises the quality of  his  customer service.
However  the illicit nature of the exchange is also obvious from  Enos 's pre-emptive warnings about keeping receipts: Customers needed to be reassured that their information would not be preserved in case  Enos  were ever caught  which  of course  is exactly what happened.
