A fire broke out after a gas canister being transferred to Gaza exploded. Two young men sustained serious burns in different parts of their bodies and were transferred to Nasser Medical Complex to receive treatment, al-Qidra said.
He added that a third citizen broke his pelvis while working in one of the tunnels, and he was taken to Abu Yousef al-Najjar Hospital in Gaza city.
Meanwhile, the Israeli occupation authorities have continued to close the Karm Abu Salem crossing in the southeast of the Gaza Strip for the sixth day respectively.
Raed Fattouh, the head of the Coordination Committee of entry of goods into the Gaza Strip, said in a press statement that the occupation authorities have continued on Tuesday to prevent the entry of goods and aid to Gaza because of the Israeli holidays.
Israel has closed the crossing since last Thursday under the pretext of rockets falling on the settlement of Sderot in the southern part of 1948-occupied Palestinian territories.
