Spokesman for Health Ministry in Gaza Ashraf Qudra has said that the victims reported during the Israeli strike on a Gaza tunnel inhaled poisonous gas during the attack.

Most of the reported victims were killed or injured from inhaling poisonous gas reportedly fired by the Israeli air force at the tunnel, he said.

Qudra stressed the urgent need to reveal the kind of weapons used in the assault.

The Israeli occupation army on Monday struck a Palestinian resistance site east of Khan Younis, south of the besieged Gaza Strip, leaving at least seven Palestinians killed and nine others injured.
