Twitter has suspended the account of dissident republican group Saoradh following the murder of Lyra McKee.
Saoradh is widely considered to be the political wing of the New IRA, which has accepted responsibility for Ms McKee's murder.
Ms McKee was shot dead during a night of rioting in the Creggan area of Londonderry last Thursday.
Following her death, Saoaradh released a statement blaming police.
The group have resisted calls to leave the stage following the murder.
Leading dissident republican Dee Fennell told the group's Easter Commemoration that the group 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 on Monday.
A number of Twitter users had been sending pictures of red stained hands to the account in response to Ms McKee's murder.
Friends of Ms McKee gathered outside Saoradh's Derry headquarters on Monday to place red handpints on the walls in protest at her death.
