Input: Consider Input: ROUGH CUT ( NO REPORTER NARRATION ) U . S . Defense Secretary Jim Mattis on Tuesday played down an apparent split between the U . S . president and his top diplomat over outreach to North Korea   saying America ' s focus was still on finding a diplomatic solution to the dispute with Pyongyang . President Donald Trump   who has traded insults and threats with North Korean leader Kim Jong Un in recent weeks   said on  Sunday Secretary of State Rex Tillerson  was " wasting  his  time " trying to negotiate with North Korea over its nuclear weapons program .  Tillerson    during a trip to China on Saturday   said the United States had direct channels of communication with the North and was probing Pyongyang to see if it was interested in dialogue . He expressed hope for reducing tensions with North Korea   which is fast advancing toward its goal of developing a nuclear - tipped missile capable of hitting the U . S . mainland . " I do not see the divergence as strongly as some ... have interpreted it  " Mattis said . " President Trump ' s guidance to both Secretary Tillerson and me has been very clearly that we would ... pursue the diplomatic effort to include with the various initiatives with China  " Mattis told a Senate hearing . " I believe that Secretary Tillerson is accurately stating that we are probing for opportunities to talk with the North . All we ' re doing is probing . We ' re not talking with them   consistent with the president ' s dismay about not talking with them before the time is right ."

Input: Consider Input: Image copyright Supplied Image caption  Hayley Smith  lost  her  job when  she  told  her  employer about  her  depression
Hayley Smith was diagnosed with chronic depression in  her  early twenties: "I'd been bottling up quite a bit through most of my teens. Then it hit me a like a brick wall "  she  said.
 She  was so depressed  she  didn't leave the house for six months.
Things began to improve and when  she  was 23 years-old  she  got a job at a food and drink company. But  she  had weekly counselling to attend.
"Every Thursday I'd have to take the afternoon off. So I spoke to my boss. In the meeting  she  was fine with it and said 'do what you need to do' ".
But after the meeting  she  received an email being told  she  was going to be taken off  her  accounts and that  she  should think about seeking employment at a mental health charity as "they might relate".
The manager also told people in the office: "It went round. It was horrible - I felt really exposed "  she  said.
Working there for a few further months triggered  Hayley  to experience anxiety  depression and "massive trust issues".
Eventually  she  left.  She  started  her  own company in London which  she  still runs five years on: "In the long-term it's given me awareness of mental health - and the awareness to make sure I was never going to make people feel the way I was made to feel."

Input: Consider Input: Documents released by the New Zealand Security Intelligence Service (SIS) show the then  17-year-old Christopher Lewis  shot at the Queen as  she  got out of  her  vehicle on the way to a science fair on Oct. 14 during  her  eight-day tour of the Commonwealth nation.
 âLewis  did indeed originally intend to assassinate the Queen  however did not have a suitable vantage point from which to fire  nor a sufficiently high-powered rifle for the range from the target â said a 1997 SIS memo  that was declassified in February and sent to Reuters on Thursday.
 Lewis   who intelligence documents described as a âseverely disturbedâ youth  was not charged with attempted murder or treason  adding to claims the incident was downplayed to prevent embarrassment to a country hosting a royal visit.
According to intelligence documents  police kept a close eye on  Lewis  during a 1986 visit by the Queen to New Zealand  fearing that  he  was still a risk.
More than a decade after the incident   Lewis  was charged with the brutal murder of an Auckland mother and the abduction of  her  baby daughter  who was later dropped at a nearby church.
According to multiple news reports at the time   Lewis  electrocuted  himself  while in prison in 1997 awaiting the murder trial.  He  denied the murder charge in a suicide note.
