Israel launched an airstrike on a car in Gaza City on Wednesday, killing the top commander of the Islamic Jihad militant group, Palestinian police said. Khaled Dahdouh, 39, was targeted in the attack, police said. The Israeli military had no immediate comment. Abu Dajana, a spokesman for Islamic Jihad's military wing, vowed revenge. "Our retaliation and our reprisal will reach into the depths of the Zionist entity," Abu Dajana said. "The Zionists will swallow the same bitter drink that each Palestinian family has drunk from."The car, hit as it traveled over a speed bump, was incinerated. Hospital officials said two other people were wounded. The explosion took place on a busy street in a residential area near the Finance Ministry compound in Gaza City. It knocked out electricity in the area and damaged several cars parked nearby. Israel last targeted militants in early February airstrikes, killing leading members of Islamic Jihad and the Al Aqsa Martyrs Brigades, a violent offshoot of Palestinian leader Mahmoud Abbas' Fatah movement.
