Two Palestinian fighters were killed and two others were wounded on Tuesday in an explosion that ripped through a Hamas training camp in the central Gaza Strip, Hamas Islamists and medical officials said.
A Palestinian security source said the blast appeared to have been an accident involving explosives rather than an Israeli attack.
Hamas stopped short of blaming Israel, which has halted military operations as part of an Egyptian-brokered truce.
An Israeli military spokesman said the army was not aware of any Israeli involvement in the blast.
