GAZA (CNN) — Two Palestinians were killed and one was critically injured Friday after an Israeli airstrike against a car in Gaza City, according to Palestinian medical officials.

One of the men killed was identified as Mahmoud Ahmad Al-Hanini, a Hamas military leader originally from the northern West Bank city of Nablus.

Al-Hanini was deported to Gaza about five years ago after being freed from an Israeli prison.

The second man was identified as Zuhair Al-Qaisy, according to the medical officials.

Al-Qaisy is considered a leader in the Popular Resistance Committees, a Gaza-based militant group.

Both Al-Hanini and Al-Qaisy were traveling in a police vehicle in Gaza City when the airstrike occurred, killing them both, the officials said.

An Israel Defense Forces spokesman confirmed that there was Israeli air force activity in Gaza City.

According to an IDF statement, the men were “part of the terror infrastructure used to execute attacks via the Sinai Peninsula, and the Israel-Egypt border, while violating Egyptian sovereignty.”

It blamed Al-Qaisy for helping to orchestrate an August 2011 attack that left 40 people injured, coordinating rocket attacks against Israel and transferring funds from Hezbollah to militant groups in the Gaza Strip.
