An Israeli air strike targeting a car in the Gaza Strip killed two terrorists Friday, medics said, hours after a bomb exploded near troops manning Israel's security fence. Gazan medical sources said the raids struck near the home of Ismail Haniyeh, former Hamas "prime minister" who stepped down June 2 when the PA and Hamas set up a unity government. The IDF identified the two dead terrorists as Osama Hasoumi and Mohammed Fatsih , and said they were targeted for their involvement in recent rocket fire against Israeli communities in the Israel's southern Negev region. The pair were traveling together in a car when they were targeted in an Israeli Air Force strike. An IDF statement said Israel held Gaza's Hamas rulers responsible for any rocket fire against Israel. Earlier Friday, five people were wounded by Israeli tank fire in response to the detonation of the border bomb. A spokesman for Gaza's health services, Ashraf al-Qudra, told AFP the five were hurt after the tanks targeted "two mosque minarets" east of Khan Yunis in southern Gaza. An 11-year-old boy was in serious condition from that attack, he said. The Israeli military said "an explosive device was activated against (army) forces operating adjacent to the security fence in the southern Gaza Strip," causing no injuries. "The force responded with tank fire towards lookout posts used to guide the attack against the forces," it said. An army spokeswoman told AFP nine explosive devices were set off at Israeli forces near the border with Gaza since the beginning of the year. While there has been no recent rise in roadside explosions near Gaza, there has been a noticeable uptick in terrorist rocket fire from Gaza targeting Israeli civilian population centers in recent weeks.
