GAZA CITY, Gaza Strip, AP -A large explosion ripped through a house in northern Gaza on Monday, killing a member of the Hamas militant group and wounding two other people, including his 8-year-old son, hospital officials said.

There were no details on the cause of the blast in Jebaliya. The dead man, identified as Ahmed Sari, taught children Islamic studies in his house, residents said.

The Israeli army said it wasn’t involved in the incident. The army frequently carries out airstrikes against Palestinian militants and typically claims responsibility for such actions.

Dozens of militants have been killed accidentally while handling explosives.

Hundreds of people, including dozens of weeping women, gathered outside the house after the explosion. Fire engines raced to the scene and rescue crews searched for people in the rubble.
