JERUSALEM — The Israeli military says a rocket fired from the Gaza Strip has landed in a street in the southern town of Sderot.

No one was wounded in Wednesday’s attack but it marked a rare incident of rocket fire penetrating Israeli’s aerial defense system. Only a handful of projectiles have struck the previously battered town since the conclusion of a 50-day war between Israel and Gaza militants in the summer of 2014.

Sirens wailed in Sderot warning of the incoming rocket, which landed near a school. Palestinians reported Israeli airstrike reprisals against Hamas positions in Gaza. No injuries were reported.

Since the 2014 war, a cease-fire has largely held. But militants in Gaza occasionally launch rockets toward Israel. Israel holds Gaza’s Hamas rulers responsible for all attacks emanating from the territory.
