Pictures of a BBC worker cradling the body of his 11-month-old baby son after a Gaza strike have emerged online.
Jihad Misharawi, of BBC Arabic, lost baby Omar after his house was struck in Israel's air strike on Wednesday.
Mr Misharawi's sister-in-law was killed and his brother was seriously injured in the attack.
BBC Foreign Editor Jon Williams this morning tweeted an image of the tragedy and a message of thanks to everyone who had sent condolences to his colleague.
The strikes came after Hamas's top military commander Ahmed Said Khalil al-Jabari was killed in Gaza on Wednesday.
Thirteen Palestinians were killed in the ensuring Israeli operation, the BBC reports, although it is unknown if Mr Misharawi's son and sister-in-law are included in this figure.
On Thursday morning three Israelis were killed after rockets were fired from Gaza.
