Prosecutors in the home city of the Polish aid worker killed in Gaza have launched an investigation into his killing, state news agency PAP reported on Wednesday.
"We have started an investigation into the killing of Polish citizen Damian Sobol on April 1-2 in the Gaza Strip as a result of an attack by the Israeli armed forces using explosives," Beata Starzecka, the deputy District Prosecutor in Przemysl, told PAP.
Earlier, Poland's foreign minister asked the Israeli ambassador in Warsaw for "urgent explanations" after a Polish volunteer was killed while providing aid in Gaza.
Citizens from Australia, Britain and Poland were among seven people working for celebrity chef Jose Andres' World Central Kitchen who were killed in an Israeli airstrike in central Gaza on Monday, the NGO said.
"I personally asked the Israeli ambassador @YacovLivne for urgent explanations," Radoslaw Sikorski wrote on social media platform X.
"He assured me that Poland would soon receive the results of the investigation into this tragedy. I join in my condolences to the family of our brave volunteer and all civilian victims in the Gaza Strip."
