Three senior Hamas military commanders have been killed in Israeli air strike in the Gaza Strip, the Islamist militant group said.

Hamas named the men as Mohammed Abu Shammala, Raed al-Attar and Mohammed Barhoum and said they were killed in a bombing of a house in the southern town of Rafah.

The Israeli military had no immediate comment on what would be the killing of the most senior Hamas men since Israel launched its offensive in the Palestinian enclave on July 8.
