Ben Cosgrove of LIFE says,
In light of today's shattering news about Tim Hetherington and our colleague, Getty photographer Chris Hondros, we did the only thing we could to keep from going crazy with anger and sadness: we built galleries of their work -- including the genuinely frightening pictures that Chris made today in Misrata, Libya, shortly before he was so badly injured (above, and below).
Both of these guys were absolutely first-rate, fearless journalists. This is Tim's haunting last tweet, before he was killed:
"In besieged Libyan city of Misrata. Indiscriminate shelling by Qaddafi forces. No sign of NATO."
Getty has since confirmed that Chris Hondros also died from his wounds.
