A BBC Arabic journalist whose baby was killed by shrapnel in Gaza has been speaking about his son's death.

Jehad Misharawi said his 11-month-old son Omar died after shrapnel hit the family home in Gaza.

Violence has been escalating across Gaza and southern Israel following the Israeli killing of Hamas' military chief on Wednesday, as Jon Donnison explains.

This report was first broadcast in November 2012

UPDATE (12 March 2013): A draft report by the UN Office of the High Commissioner for Human Rights said that Omar Mashhrawi, the 11-month-old son of a BBC journalist in Gaza, may have been killed by a Palestinian rocket, not an Israeli one.
