Via LibyaFeb17.com and via the Twitter updates from NPR's Andy Carvin, terrible news that the brave citizen journalist Mohammed Al-Nabbous, known to fans as "Mo," was killed last night.

From currently available information, it appears Mo was killed in a firefight, while recording.

Mo created and operated the widely-viewed live video channel Al Hurra TV on Livestream, broadcasting raw footage and commentary from Benghazi, Libya.

Andy Carvin writes:

Mohammad Nabbous was my primary contact in Libya, and the face of Libyan citizen journalism. And now he's dead, killed in a firefight. A few hours ago he went out to record some more audio and was caught in a firefight. [Link]. Audio stops 6:30 into it. For several hours we heard rumors that he had been shot but we didn't want to say anything until we knew for sure. And now I can't stop thinking, what if those French planes began to arrive 12 hours ago. Would Mo be alive now? I just don't know.

Nabbous' wife, speaking on his Livestream channel earlier:

I need everyone to do as much as they can for this cause. They are still shooting. More people will die. Don't let Mo's life go in vain.

Here was one of Mo's early reports.

Here was his last.
