GAZA STRIP - IAF (Israeli Air Force) helicopter gun ships targeted a Hamas security outpost in Khan Younis in central Gaza overnight Wednesday.

The air strike came in response to ongoing Palestinian rocket and mortar shell fire on southern Israel.

There were no injuries, but the facility, which was targeted during Israel's three-week military operation in the Gaza Strip, sustained further damage.

"The IDF attacked a Hamas position in response to mortars fired Wednesday against southern Israel," an IDF spokesman confirmed.

Since the Israeli government declared a unilateral cease-fire on January 18, followed 12 hours later by Hamas, Gaza-based Palestinians have fired more than 40 Kassam rockets, mortar shells and Grad Katyusha missiles on western Negev communities.

On Wednesday, three mortar shells exploded in the Eshkol Regional Council, the first in mid-afternoon and two others just before 7:00 p.m. No injuries or property damage was reported.

About 9:30 Tuesday evening, a half hour before polls closed, a Kassam hit between the Sha'ar Hanegev and Sdot Negion Regional Council. No one was injured and there was no property damage in the attack.

Sunday morning, a Kassam hit a parking lot, heavily damaging several cars, which caught on fire, but no one was injured.
