According to Reuters, the attack took place on August 18 local time in the city of Deir Al-Balah in the central Gaza Strip.
The Palestinian health authority said this was an air strike and it killed 19 people, including 6 children. Currently, Israel has not made any official announcement about this.
On the same day, US Secretary of State Antony Blinken arrived in Israel to participate in a negotiation with Egypt and Qatar to come up with mediation options to stop fighting in the region.
This is the 10th time the US Secretary of State has come to Israel since the war began last October.
The three countries have met many times to discuss this, the most recent being a two-day meeting that took place in Qatar's capital Doha last week.
They are trying to convince Israel to reduce air strikes and Iran to limit "retaliation" actions after the assassination of the leader of Hamas on July 31 to avoid an escalation of tensions in the region.
Not long ago, the Israeli army also used fighter jets to bomb a school that sheltered thousands of people in Gaza. About 100 people died , including women and children.
The cause of the attack was because Israel said they discovered this area was a secret base for Hamas and they wanted this force to suffer damage.
The Egyptian Ministry of Foreign Affairs strongly condemned the airstrike, although the Israeli military took many actions to minimize damage such as limiting the amount of ammunition or improving the accuracy of each shot.
