Israeli strikes have pummeled the Gaza Strip for three days, killing at least 30 people, among them children and leaders of the Islamic Jihad militant group, according to Gaza’s health ministry. Israeli officials say their forces are targeting commanders of and weapons stored by the extremist group.

Islamic Jihad has fired hundreds of retaliatory rockets into Israel — with some reaching as far as central Tel Aviv — but most were intercepted by the country’s air defense system, according to the Israel Defense Forces. An Israeli man died Thursday in a rocket attack on the city of Rehovot.
