TWO Palestinian children — a brother and sister — were killed on Saturday when an Israeli air raid hit their home in the besieged Gaza Strip.

Gaza Health Ministry spokesman Ashraf al-Qidra confirmed that six-year-old Israa Abu Khussa had died of her injuries hours after the attack that had already killed her 10-year-old brother Yasin.

Bomb fragments from the raid on the north-western city of Beit Lahiya hit their home, which was partially destroyed during Israel’s 2014 war on Gaza, also wounding a third sibling.

Both were buried at al-Salatin cemetery.

The Israeli air force targeted five Hamas sites after four rockets were fired from the territory into southern Israel.

Those rockets landed in open ground and caused no casualties or damage.

No militant group claimed responsibility for the rocket fire, but Israel holds governing Hamas responsible for all attacks from Gaza.

Israeli army spokesman Peter Lerner called the rocket attack an “example of incessant extremist efforts to threaten the security and safety of the people of southern Israel.”

He vowed that the armed forces would “continue to protect against those who threaten innocent lives and Israel’s sovereignty,” adding that there had been a total of seven rocket attacks from Gaza since the start of the year.

Gaza civil defence rescuers found the bodies of two Palestinian workers yesterday in a smuggling tunnel that Egyptian authorities had flooded with seawater days before.

The two were named as Fadi Abu Dan from Khan Yunis and Muhammad Abbas from Rafah.
