How can the deaths of Palestinians in Gaza be monitored by outside organisations? Nearly 19,000 people have been killed in 10 weeks of war, according to the Hamas-run health authorities.

She told us that so far, the estimates from the Hamas-run health authorities are consistent with Airwars' own findings.
