military source said.
"The responsibility for this attack rests with Hamas," Israeli Deputy
Foreign Minister Danny Ayalon said.

"I truly hope that Hamas will surprise us and join a collective battle,
rather than settle for calling on the Palestinians to prepare for an
uprising in the West Bank," Dahlan said.
In 2010, more than 30 missiles were fired from the Gaza Strip into
Israel. The attack that killed the 30-year-old Thai worker was said to have
been the work of the Al Qaida-aligned Ansar Al Sunna, which claimed
The Israel Air Force has responded to the Palestinian strikes by attacks
on suspected Hamas missile arsenals and weapons tunnels in the southern Gaza
Strip. Army units also fired artillery shells toward Gaza City.
