Two other men were charged last week.
Two more men have been arrested in connection with the murder of Lyra McKee.
Two men aged 24 and 29 have been arrested in Derry this morning under the Terrorism Act and have been taken to the Serious Crime Suite at Musgrave Police Station.
Journalist Lyra McKee was shot and killed by dissident republicans in the Creggan area of Derry city as she observed rioting that was going on in 2019.
Two men were charged with the murder of journalist last week, aged 21 and 33. They have also been charged with arson, possession of petrol bombs, possession of a firearm and ammunition with intent to endanger life. The older man was also charged with robbery.
Additionally, a third man was charged with the possession and throwing of petrol bombs and riot.
Brandon Lewis, the Northern Ireland Secretary, welcomed the update in the case.
In a statement, he said that McKee’s murder was a “reminder that a small minority of individuals continue to seek to cause harm to communities.”
He continued: “This was an utterly senseless and shocking crime and I applaud the continued work of the PSNI to bring those responsible to justice.
“The fact that serious charges have been brought forward, which includes two individuals being charged with Lyra’s murder, is to be strongly welcomed and is a testimony to that hard work.”
