GAZA CITY, Gaza Strip (AP) — Israeli aircraft conducted strikes early Tuesday on Islamic Jihad targets in the Gaza Strip, the Israeli military said, and residents reported blasts in the Palestinian enclave.

Witnesses said an explosion hit the top floor of an apartment building in Gaza City and a house in the southern city of Rafah. Palestinian media said several people were injured. There was no immediate confirmation from health authorities.

The airstrikes come as tension boils between Israel and militants in the Gaza Strip, which is ruled by the militant Hamas group.

In anticipation of Palestinian rocket attacks in response to the airstrikes, the Israeli military issued instructions advising residents of communities within 25 miles (40 kilometers) of Gaza to stay close to designated bomb shelters.

Last week, Gaza militants fired several salvos of rockets toward southern Israel, and Israeli military responded with airstrikes following the death of a hunger-striking senior member of the Islamic Jihad in Israeli custody.

The airstrikes are similar to ones in 2022 in which Israel bombed places housing commanders of Islamic Jihad group, setting off a three-day blitz that saw the Iranian-backed group loosing its two top commanders and other dozens of militants.
