The Gaza Health Ministry said three Palestinians were killed Wednesday in Israeli strikes east of Gaza City.
The Israeli military said it was "targeting Hamas military posts in the Gaza Strip" after Israeli troops on the border came under fire. An Israeli officer was also wounded by a Palestinian sniper.
The latest clash comes days after Gaza's Hamas leaders and Israel agreed to a cease-fire in an attempt to de-escalate hostilities. The cease-fire was broken last weekend when an Israeli soldier was killed by a Palestinian sniper.
Israel retaliated with a massive offensive that raised fears of another war between Israel and Hamas, which have fought three wars since 2008.
