One of Britain's most famous journalists has written that his reporting in Gaza has affected him as nothing he has ever witnessed.

Jon Snow, who has anchored "Channel 4 News" in the UK for 25 years, recently traveled to the Palestinian territory to report on the Israeli invasion. In a blog post on Friday, he wrote, "I feel guilty in leaving, and for the first time in my reporting life, scarred, deeply scarred by what I have seen, some of it too terrible to put on the screen."

Snow spent a great deal of time at the Shifa hospital in Gaza, where many of the hundreds of children killed or wounded by Israeli strikes have been treated. In a segment on his Friday broadcast, he said that he'd seen children suffering in ways that he could not get out of his mind.

"The idea in the looseness of a war zone that you can control your children, that they won't be somewhere where they can be hit is beyond any kind of imagination," he said.

In the blog post, Snow wrote about what it was like to return to London after what he had seen.

"Leaving Israel and beleaguered Gaza far below me, I lay back in my BA seat headed for London. I donned my headphones and listened to Bach’s heavenly violin concerto in E major, and wept, as I rarely have as an adult," he wrote.
