The Israeli military has said an initial investigation into a strike that sparked a deadly weekend fire in a tent camp in the southern Gaza city of Rafah found the blaze was caused by a secondary explosion.

Rear Admiral Daniel Hagari, the chief military spokesman, said the military fired two 17-kilogram munitions that targeted two senior Hamas militants.
