A grim new feud opened up on social media on Thursday as pictures were traded of babies who died or were injured during the conflict in Gaza.

Pictures emerged of BBC cameraman Jihad Misharawi's 11-month-old son Omar, who was killed on Wednesday during an Israeli attack. Misharawi's sister-in-law also died in the strike on Gaza City, and his brother was seriously injured.

Misharawi told BBC Arabic:

Shrapnel hit our house. My sister-in-law was killed along with my son. And my brother and my other son were wounded.

What did my son to to die like this? What was his mistake? He is 10 or 11 months old, what did he do?

We are not the resistance, there are no fighters in my house.

A picture of Omar was posted on Twitter by BBC Middle East bureau chief Paul Danahar.

Soon after, Israeli prime minister Binyamin Netanyahu posted what was seen as a response, tweeting this picture of a baby reportedly injured in today's rocket attack on Kiryat Malachi. "Hamas deliberately targets our children," Netanyahu wrote.

I saw today a picture of a bleeding Israeli baby. #Hamas deliberately targets our children bit.ly/W9uYkA twitter.com/netanyahu/stat…

Three people were killed during the Kiryat Malachi rocket attack, and a four-year-old boy and two babies were also wounded.
