This is award winning investigative journalist, who does not work for the Sun, Robert Parry's full article.
"If the U.S. intelligence analysts are correct – that the rebels and Russia are likely not responsible – the chief remaining suspect would be the Ukrainian government, which does possess Buk anti-aircraft missiles and reportedly had two fighter jets in the vicinity of Malaysia Airlines Flight 17 at the time of the shoot-down."

Just to show what type of journalist Robert Parry is, since journalist is also a term misused for employees of the Sun, here is more information on what Robert Parry did from wikipedia
"In August 1990 PBS' Frontline asked Parry to work on the October Surprise conspiracy theory ,[1] leading to Parry making several documentaries for the program,[6][7][8] broadcast in 1991 and 1992. He continued to pursue it after a Congressional investigation had concluded the story was untrue , turning his Frontline research into a book published in 1993,[9] and in 1994 he unearthed "a treasure-trove of government documents" supporting the theory,[6] "showing that the [Congressional] task force suppressed incriminating CIA testimony and excluded evidence of big-money links between wealthy Republicans and Carter's Iranian intermediary, Cyrus Hashemi".[3] In 1996 Salon.com wrote about his work on the theory, saying that "his continuing quest to unearth the facts of the alleged October Surprise has made him persona non grata among those who worship at the altar of conventional wisdom."[6]
When journalist Gary Webb published his newspaper series Dark Alliance in 1996 alleging that the Reagan administration had allowed the Contras to smuggle cocaine into the US to make money for their efforts, Parry supported Webb amidst heavy criticism from the media.[10]"

I didn't realise that Robert Parry had anything to do with Gary Webb, who is a person whose "suicide" is a well-known topic among advanced conspiracy theorists.
