Two sides exchange deadly airstrikes, rocket attacks.
NBC News -- The head of the militant wing of the Palestinian Hamas movement and seven others were killed as Israel launched a series of airstrikes in Gaza Wednesday, officials said.
Hamas spokesman Fauazy Brehom told NBC News that Ahmed Jabari was killed in the attack by Israeli forces. Jabari was the most senior commander of Hamas' military wing, the Ezzidine Al-Qassam Brigades.
A statement from the Al-Qassam Brigades said that Israel had “opened the gates of hell.”
In a frequently updated live blog chronicling the attacks, the Israel Defense Forces claimed it had targeted "dozens" of Hamas’ medium-range underground rocket launch sites and other weapons storage facilities. The report said Israel had also intercepted 17 rockets fired from Gaza.
"If I were a senior Hamas activist - I would look for a place to hide," IDF spokesman Brgi. Gen. Yoav (Poly) Moredechai said in a statement published online.
