Israeli forces attacked positions belonging to Hamas movement in the Gaza Strip after rockets were fired from the Palestinian enclave, the military said early Saturday.
Late Friday, "five projectiles were launched from the Gaza Strip towards Israel," the army said.
The projectiles hit open fields in southern Israel, army spokesman told Agence France Presse.
In response, an "aircraft and tank struck a number of Hamas military targets in the northern Gaza Strip, including a post and military positions," the army said in a statement.
A Hamas security source said there were no casualties resulting from the Israeli strikes.
The exchange came hours after two Palestinian teenagers were killed by Israeli fire during clashes on the Gaza border.
The Palestinians aged 14 and 17 were shot dead by Israeli forces, the Gaza health ministry said, with another 46 Palestinians wounded.
The Israeli army said thousands of Palestinians took part in the demonstrations along the border fence, which included throwing "fire bombs and explosive devices" at soldiers.
Palestinians have been holding regular mass protests along the fortified border since March 2018.
