Twitter has suspended the account of dissident republican group Saoradh following the murder of Lyra McKee.
Saoradh spokesman Paddy Gallagher said the party was aware the account had been suspended, but declined to comment further.
Twitter said: "We have clear terms of service in place which we enforce when violations are identified."
According to its terms of service, common reasons for suspending a Twitter account include spam, account security at risk and abusive tweets or behaviour.
Saoradh is widely considered to be the political wing of the New IRA, which has admitted responsibility for Ms McKee's murder.
Following her death last Thursday night, Saoradh released a statement blaming police.
The group has resisted calls to leave the stage following the murder.
On Monday, Dee Fennell, one of its prominent members, told the group's Easter commemoration in west Belfast that Saoradh would not be "going away".
"We will continue to engage ourselves in activism in the course of this year and in future years, I just want to make that absolutely and abundantly clear," he told the assembled crowd at Milltown Cemetery.
Hundreds of Twitter users had been sending pictures of red stained hands to Saoradh's account in response to Ms McKee's murder.
It came after her friends and supporters gathered outside Saoradh's Londonderry headquarters on Monday to place red handprints on the walls in protest at her death.
