Israel Defense Forces tank fire struck a home in the Gaza Strip on Tuesday killing four Palestinians and wounding another three, including children, Gaza hospital officials said.
The Israeli military had no immediate comment on the report, but said earlier that four rockets had been fired at Israel from the Strip during the day.
Israel has stepped up retaliatory strikes since a barrage of rocket fire was aimed at its towns in recent days from Gaza, which is ruled by the Hamas.
Palestinian medics said the dead youths were aged 12, 16 and 17. The 58-year-old owner of the house was also killed.
Locals said four Israeli tank shells struck the building east of Gaza City.
On Saturday, southern Israel was hit by over 50 rockets, of which Hamas claimed responsibility for 10. The Israeli Air Force struck Gaza targets in retaliation for the bombardment.
On Monday, an IAF fighter jet struck a Gaza tunnel running along the border with Israel, as well as Hamas militants in the northern Gaza strip, an IDF statement confirmed.
The IDF spokesperson's office released a statement saying that the Gaza tunnel was used to smuggle terrorists into Israeli territory with the intent to execute attacks against Israeli citizens.
