A veteran TV cameraman for Britain's Sky News was shot and killed while covering the deadly violence in Cairo on Wednesday, the channel said.
Mick Deane, a 61-year-old father of two boys, had worked at Sky for 15 years. A British citizen, he had been based in Washington and, for the past two years, in Jerusalem.
The head of Sky News, John Ryley, paid tribute to a "talented and experienced" journalist while British Prime Minister David Cameron said he was "saddened" by the news.
Deane was the second journalist to be killed in the Egyptian capital on Wednesday, when more than 120 people were killed as security forces stormed camps occupied by supporters of ousted president Mohamed Morsi.
Habiba Ahmad Abdel Aziz, a 26-year-old reporter for the Xpress supplement of the Dubai-based Gulf News, died as troops clashed with Morsi supporters.
She was not working at the time, only visiting. It is believed her father is an advisor to Morsi.
Deane was shot and wounded while reporting in a team with Sky News' Middle East correspondent Sam Kiley. The cameraman received medical treatment, but died shortly afterwards.
None of the other members of the team were injured, Sky said.
Foreign affairs editor Tim Marshall paid an emotional tribute to Deane on air, saying: "He was a friend. Our hearts go out to his family.

"He died doing what he'd been doing so brilliantly for decades."
Sky's political editor Adam Boulton described him as "the nicest, the best, the bravest".
Ryley said: "Everyone at Sky News is shocked and saddened by Mick's death. He was a talented and experienced journalist who had worked with Sky News for many years."
At least 124 people were killed in the Rabaa al-Adawiya camp alone on Wednesday, according to an AFP count, after security forces stormed two huge Cairo camps occupied for weeks by Morsi supporters.
Reporters Without Borders told AFP that four other journalists, all Egyptians, were injured in Wednesday's clashes.
Three were photographers and cameramen while one was a reporter.
The US-based Committee to Protect Journalists (CPJ) condemned the death of the Sky News cameraman and called for the Egyptian authorities to bring the culprit to justice.
"The killing of Mick Deane underscores the urgent need for such action and for all sides to show restraint and allow the media to do their job," CPJ Deputy Director Robert Mahoney said.
"The authorities must investigate all attacks on journalists and hold those responsible to account."
The CPJ has documented at least 78 assaults on journalists from August 2012 until Morsi was ousted on July 3, 2013.
