GAZA CITY (Ma'an) -- Israeli tank shells killed 3 Palestinians and wounded 25 in the Gaza Strip on Saturday, medics and witnesses said.
Ahmad al-Dardasawi, 18, and Muhammad Hararah, 17, were killed in Gaza City, and a third unidentified man later died from injuries sustained in the attack.
At least 21 people were wounded in the shelling, with 10 said to be in a serious condition.
Four people were also wounded in Khan Younis as Israel's army targeted an area east of city, witnesses said.
The casualty toll is one of the highest in a single incident in Gaza in recent months.
Ambulances and private vehicles rushed the wounded to hospital, local eyewitnesses said.
The Israeli military declined immediate comment on the incident.
Hamid Younis Abu Daqqa, 13, was killed on Thursday after Israeli forces targeted houses and farms east of Khan Younis, according to Ashraf al-Qidra, a medical spokesman in Gaza.
Medics said the boy was hit by machine gun fire, either from Israeli helicopters or tanks that took part in the incident.
A military spokeswoman said Israeli troops came under fire during "routine activity" in the area, and returned fire in the direction of the suspects.
On Tuesday, three Israeli soldiers were wounded by an explosive device in the southern Gaza Strip, Israel's army said.
A day earlier, Israeli soldiers shot and killed a 20-year-old Palestinian man who approached a fence near Gaza's border with Israel, medics said.
Medics had to wait around six hours for permission to pick him up from the spot near al-Bureij refugee camp. They suspected he died of injuries for which he might have been treated.
