Israel says it has killed a senior Islamic Jihad commander in a crowded Gaza refugee camp, the second such targeted attack since it launched its a military offensive against the militant group just before the weekend.

The Iran-backed militant group has fired hundreds of rockets at Israel in response, and the risk of the cross-border fighting turning into a full-fledged war remains high.
