- [Chris] On Thursday and Friday, fighting

filled the skies around southern Israel.

Israel's Iron Dome defense system

intercepted severalrockets fired into Israel

by Islamic groups inside Gaza.

Israeli war planes retaliated by hitting

Hamas military installations.

The IDF released a graphic marking sites

they targeted, including an underground

rocket manufacturing site, and a weapons

manufacturing site.

Hamas, a terror organization, dedicated

to Israel's destructiondenied responsibility.

But the IDF held them accountable

for what happens inside Gaza.

The Iranian backed Islamic Jihad

also has a formidable rocket arsenal

inside the Gaza Strip.

The fighting began on Thursday,

when sirens wailed throughout Tel Aviv,

after Islamic groups fired two rockets

toward Israel's second largest city.

Israel's Channel 10 reported the rockets

were Iranian made, afterthe rocket attacks,

Israeli Prime Minister,Benjamin Netanyahu,

met with security officials

at the Defense Ministry in Tel Aviv

to discuss a response.

Some Israelis seem unfazed.

- I took my dog for awalk, there was a siren.

Honestly, I didn't know if it was here

in the neighborhoodbecause it was a bit low.

And I thought maybe, from a nearby area.

Anyway, as we do, we went into a building

we heard an explosion, we went out

and that's it, we move on.

- [Chris] Hamas and Israelhave fought three wars

since Hamas took controlof the Gaza Strip in 2007,

whether this situationwill escalate is unclear.

The escalation comes as Jerusalem holds

its annual marathon and just weeks

before Israelis elect a new government.
