Israeli aircraft fired two missiles at a home in a northern Gaza refugee camp late Monday, lightly wounding two bystanders, medical officials said.

The owner of the home, an activist with the Islamic Jihad militant group, was not home at the time. The owner, Mohammed Asliya, said he had been warned by the army shortly before the airstrike to leave the house.

The army said the home had been used to store weapons.

Israel has been conducting an offensive in Gaza for nearly two months since militants crossed the border and captured an Israeli soldier. The soldier still has not been freed.
