CBS News correspondent Mark Phillips zip lined above London in memory of CBS News colleagues Paul Douglas and James Brolan, who were killed by a roadside bomb in Baghdad nine years ago. Phillips is raising money for the Rory Peck Trust, which supports freelance journalists.
CBS is also remembering Douglas and Brolan by running, cycling and swimming in the London Triathlon in August. CBS News London will enter nine teams who will swim 750m, cycle 20km and run 5k.
