One Palestinian was killed on Saturday in an Israeli air strike on a Hamas training camp in the Gaza Strip in response to a barrage of rockets from the coastal enclave.
Gaza's Health Ministry said Ahmed al-Shehri, 27, died from shrapnel injuries during the Israeli bombings that continued through the early hours of Saturday.
It was not immediately clear whether he was a civilian or a gunman.
Three other people were wounded in the attack. Witnesses at Nasser Hospital in the southern city of Khan Younis said the three were sitting in an orchard adjacent to one of the Hamas posts that was hit.
The Israeli military said that Palestinians fired 10 rockets from Gaza into Israel late on Friday, eight of which were intercepted. Police said one projectile had hit a house in a town near the border, causing damage but not casualties.
In response, the military said, a series of Israeli strikes targeted sites belonging to Hamas.
The army "views the rocket attack targeting Israeli territory with great severity and is prepared to continue operating as necessary against attempts to harm Israeli civilians," the military said.
None of the armed groups in Gaza claimed responsibility for firing the rockets. The Israeli military said Hamas was ultimately responsible for the attack.
Israel and Hamas have fought three wars over the past decade and cross-border tensions are high and such flare-ups are not rare.
Israel pulled its troops and settlers from the narrow coastal strip in 2005 but keeps the enclave under a blockade, citing security concerns. About 2 million Palestinians live in Gaza.
Earlier Friday, health officials said scores of Palestinians were wounded by live fire during protests along Gaza-Israel border fence.
Hamas launched the weekly demonstrations last year against 12-year-old Israeli blockade.
International mediators, including Egypt, Qatar and the United Nations, oversee the ceasefire between Hamas and Israel to lower the intensity of the protests and pacify the border area in exchange for humanitarian projects in the seaside enclave. Hamas charges Israel of not honoring the agreement by slowing the implementation of the deal.
