CAIRO (Reuters) - Four children were killed and five other people were injured when a rocket landed near their homes in Rafah, an Egyptian town in Sinai near the border with Gaza, security officials said on Saturday.

Three security sources said the rocket was likely fired by Islamist militants operating in the Sinai peninsula, which borders Israel and the Palestinian Gaza Strip.

The state news agency MENA said security officials were still investigating where the rocket had come from.
