MOSHAV NATIV HA'ASARA, Israel - Israel is promising harsh response to a deadly rocket attack from Gaza, Thursday.

Shrapnel from a Kassam rocket fired by Palestinian terrorists in the Gaza Strip killed a 30-year-old agricultural worker from Thailand. The rocket landed in a greenhouse just outside the Gaza Strip.

An al Qaeda-linked terrorist group has claimed responsibility, saying the attack was for Israel's "judaization" of Muslim holy places in Jerusalem.

Thursday's incident was the third rocket attack in less than 24 hours.

Paramedics, who transported the injured man to a medical facility on Moshav Nativ Ha'asara in the Ashkelon Coast Regional Council, were unable to save him.

"A Color Red siren was sounded," a local resident said. "We ran to find cover, and 20 seconds later, we heard a very loud explosion. I saw the smoke and realized it hit a greenhouse belonging to one of the residents where a group of Thai workers was employed," he said.

"To the best of my knowledge, there are concrete [bomb] shelters, and one could have made it there on time, but apparently the workers didn't heed the siren," he said.

The Ansar al-Suna Brigades, an al-Qaeda affiliated Palestinian group in Gaza, claimed responsibility for the attack.

Thursday's deadly attack took place as European Union foreign policy chief Catherine Ashton from England was visiting the Gaza Strip.

On Wednesday night, paramedics evacuated a woman and a young girl to a shock treatment center after two Kassam rockets exploded near the town of Sderot.
