Israel bombs Gaza 'underground' complex after blast

Israel's military carried out an air raid overnight against an underground Hamas facility in the Gaza Strip and destroyed a separate tunnel under construction that could be used for attacks, it said today.

No casualties were reported in either operation, which came after an explosive device was detonated near the Gaza border with Israel, the latest in a string of such incidents.

Israel's military said the operation to destroy the tunnel involved new technology it has been working on to detect them.

"Our policy is to act resolutely against any attempt to harm us and systematically eliminate the terror tunnel infrastructure, and we will continue doing so," Israeli Prime Minister Benjamin Netanyahu said in a statement.

The new tunnel under construction by Hamas, the Islamist movement that runs the Gaza Strip, was being dug to link up with an older one in the south of the Palestinian enclave, according to military spokesman Jonathan Conricus.

The new tunnel had not reached Israeli territory and was within several hundred metres of the border fence, near the Kerem Shalom goods crossing and in the area of the city of Rafah in the Gaza Strip, he said.

Israel had been monitoring the work before the operation, said Conricus.

It was destroyed by filling it with an unspecified material and explosives were not used, he said, declining to elaborate further.

Israeli soldiers carried out the operation from the Israeli side of the border fence, he said.

Conricus also did not describe in more detail what he said was an underground facility struck in the air raid in the central Gaza Strip.

"It was a subterranean complex, a military complex," he said.

Gaza resident Amal Malaka spoke of her fear as the strike was occurring.

"We heard the sound of shelling, the whole of the house shaking and the windows too," she told AFP.

"My children were afraid and the girls fell down from the bed."
