Kingsmill video controversy makes lead in NI newspapers
Controversy over a video tweeted by Sinn Féin MP Barry McElduff features on the front page of Monday's papers.
He posted it on Twitter on Friday. Mr McElduff has since apologised and said he did not realise there was a link between the brand name and anniversary.
Ten Protestants were murdered by the IRA in the massacre on 5 January 1976.
It is understood the party leadership is to meet the MP on Monday to discuss the video.
The paper further reports that only one of Sinn Féin's 27 MLAs offered support to Mr McElduff on Twitter.
Colin Worton, whose brother was murdered in the attack, told the paper: "He was probably thinking that only a few of his cronies would laugh back at it, but now a whole new generation of people know what the IRA did at Kingsmills."
"Bomb parts the key to catching Kerr Killers," reports the Daily Mirror.
Detectives investigating the murder of Const Ronan Kerr believe tracing car bomb parts may hold the key to finding his killers.
Det Ch Insp John Caldwell said "significant progress" had been made in the investigation.
"The key to putting people before a court charged with Ronan's murder lies with local communities in Omagh and east Tyrone," he said.
"Ronan's family deserve to see his terrorist murderers behind bars where they belong."
Elsewhere, the Irish News reports that almost £250,000 has been spent replacing televisions in prisons in Northern Ireland over the past three years.
It is understood that the money was drawn from the Prisoners' Amenities Fund, which is used to finance activities throughout the prison system.
Since 2014-15 about £19,000 has been taken from the fund for snooker table repairs.
A spokesperson for the Prison service told the paper: "The monies paid into the Prisoners' Amenities Fund are from the tuck shop, uncollected prisoners' personal cash receipts, rental income paid for the use of the in-cell TVs and sales generated within the workshop area."
They added that everyone "committed to prison" is offered a TV in their cell for £1 per week, and is considered a privilege which can be removed if rules are broken.
Dogs to find new play park
Doggy Dynamos, which was based at the old B&Q site on the Boucher Road, was believed to be Belfast's only indoor dog park.
Pet owners that used the area said the operators closed the doors without warning over Christmas.
Maeve O'Gorman told the paper: "We were in negotiation with South 13 after trying for month to set up a pay plan.
"The next thing we know they have closed the park.
"We are absolutely heartbroken for our lovely dog and their owners."
The paper reports that a spokesperson from South 13 declined to comment.
A pensioner has been left devastated after discovering his parents' grave had been vandalised at Belfast City Cemetery, reports the Belfast Telegraph.
Andrew McAllister, 82, said those behind the damage had "no respect".
Belfast City Council has admitted that attacks are an "ongoing issue" at the City Cemetery.
It said that if a headstone is damaged the council will see that it is repaired, however, if it is damaged by natural wear and tear, repairs will be down to the grave owner.
