Leading figures from the worlds of media, politics and the arts gathered to pay an emotional tribute to "bravest of the brave" war correspondent Marie Colvin.
Ms Colvin, who was 56, was killed along with French photojournalist Remi Ochlik on 22 February, when the building that served as a makeshift media centre in the city of Homs was struck by a Syrian army mortar,
A memorial service was held at St Martin-in-the-Fields church in Trafalgar Square, London.
The congregation heard tributes to Ms Colvin from John Witherow, editor of The Sunday Times, and BBC foreign correspondent Lyse Doucet, as well as a poem composed by Alan Jenkins, deputy editor of the Times Literary Supplement and a close friend of Ms Colvin.
Those present at the service included her mother Rosemarie and sister Cat as well as Foreign Secretary William Hague, former Liberal Democrat leader Charles Kennedy and former Foreign Secretary David Miliband.
Miliband read the poem Travel, by Edna St Vincent Millay.
Witherow described Colvin as the "greatest war correspondent of her generation" whose death had sparked an outpouring of grief throughout the world."
Witherow went on to commend her spirit and courage in the face of danger.
"Losing her eye in Sri Lanka led her into such a depression that she almost gave it all up but she came back because she was excited by the Arab Spring and because she thought she could really make a difference," he said.
He added that: "Tyrants hate the spotlight of publicity because it not only exposes their abuse of power but it can sometimes stay their hand.
"If anyone could stay their hands, it was Marie, and as she showed in East Timor her bravery there did save many lives."
As well as a video tribute to Ms Colvin, musician Cerys Matthews performed Bob Dylan's Blowin' in the Wind and the Willie Nelson song Crazy, made famous by Patsy Cline.
