Friends of murdered journalist Lyra McKee are on the last leg of a three-day peace walk from Belfast to Londonderry.

Hundreds turned out at Writer's Square in Belfast on Saturday morning, many wearing T-shirts in her memory and carrying flags with messages of peace.

The 29-year-old was killed by dissident republican group the New IRA while observing clashes with police in the Creggan estate in Londonderry last month.

Taking off from Writer's Square beside St Anne's Cathedral where Lyra's funeral took place, the walk will take the participants to the Guildhall in Derry - the city where Lyra and her partner Sara lived together.

Snow Patrol frontman Gary Lightbody is also due to join them on the last leg on Monday ahead of a rally at Derry's Guildhall.
