Hamas on Saturday denounced as "barbaric" overnight strikes it said damaged a Gaza children's hospital.
Gaza's ruling Hamas in a statement said a "barbaric" Israeli strike had damaged a children's hospital and a centre for people with special needs.
Medical sources in Gaza said the strikes "lightly wounded" two civilians, including a child.
The Israeli army, however, insisted on Saturday afternoon that it did not hit the hospital.
"Secondary explosions, which were identified from the strike on the Hamas rocket manufacturing site, are suspected of causing the damage to the nearby located hospital," an army statement said.
Sirens had sounded on Friday night in the southern port city of Ashkelon and the area surrounding the Gaza Strip, according to an earlier army statement.
