The Northern Ireland secretary says the UK Government is "truly sorry" over the events in Ballymurphy in 1971.
His prepared remarks followed a Belfast judge's ruling that the 10 people fatally shot in Ballymurphy, west Belfast, in August 1971 were innocent and unarmed civilians, not Irish Republican Army gunmen as British authorities had branded them for decades.
Mr Lewis said the PM was writing to the families.
"There is no doubt that what happened on those bad few days in Ballymurphy also fuelled further violence and escalation, particularly in the early years of the Troubles".
"This government profoundly regrets and is truly sorry for these events, at how investigations after these awful events were handled and for the additional pain that the families have had to endure in their fight to clear the names of their loved ones, since they began their campaign nearly five decades ago", Mr Lewis said.

Johnson's words of contrition came in a Downing Street statement issued after he spoke by videoconference Wednesday to the joint leaders of Northern Ireland's power-sharing government, Democratic Unionist Party leader Arlene Foster and Sinn Féin vice president Michelle O'Neill.
He said it is an "insult to the families" that Boris Johnson's apology came in a conversation with others.
Relatives of the Ballymurphy dead rejected Johnson's written apology and vowed to sue the Ministry of Defence for damages.

Brandon Lewis said: "The events of Ballymurphy should never have happened, the families of those who were killed should never have had to experience the grief and trauma of that loss". They should not have had to wait this long for details about the events that unfolded between 9 - 11 August 1971.
He added that the desire for families of victims to know the truth about what happened to their loved ones was "strong and legitimate".
"We want a path forward which will also pave the way for wider societal reconciliation for all communities, allowing all the people of Northern Ireland to focus on building a shared, stable, peaceful, and prosperous future".
"Will this Prime Minister now finally apologise for what those British Forces did by murdering 10 entirely innocent people or will they continue to pursue an amnesty for their killers?"
"The Prime Minister apologised unreservedly on behalf of the UK Government for the events that took place in Ballymurphy and the huge anguish that the lengthy pursuit of truth has caused the families of those killed", Downing Street said in a statement.
