JERUSALEM — Palestinian militants fired at least 11 rockets into Israel on Friday after an airstrike against a Hamas target in Gaza that killed a Palestinian civilian.

The rockets landed in Israeli territory but caused no casualties, Israeli police spokesman Micky Rosenfeld said. Air-raid sirens and bomb shelters have helped keep civilian casualties low in southern Israel over years of rocket fire from Gaza.

The latest exchange followed several days of violence in the Hamas-ruled Gaza Strip.

Earlier Friday, Israel carried out multiple airstrikes against Hamas facilities. One damaged a house next to a targeted site, killing a 42-year-old civilian and wounding several members of his family, according to Gaza health official Adham Abu Salmia.

Other houses were damaged by fire or shrapnel and a total of 25 people were wounded, Abu Salmia said.

Israel’s military released a statement Friday expressing regret for harm to bystanders but blaming Hamas for choosing “to operate while embedded within a civilian population, using them as a human shield to protect their actions.”

The military said the civilians were not directly harmed by the airstrikes but by the explosion of rockets stored at the sites that were hit.
