We’re overjoyed to report that our four journalists missing in Libya since Tuesday morning are free and have arrived safely in Tunisia…

…And, in a week when we have dared to declare that the work we do is worth paying for, this is a reminder that real, boots-on-the-ground journalism is hard and sometimes dangerous work. To the many colleagues who are deployed in hard places — the battleground streets of North Africa and the Middle East, the battered landscape of Japan — we implore you to be careful.
