Israel accuses Syria, Iran of orchestrating Gaza rocket fire

The Israeli army accused the Syrian government on Saturday of ordering Palestinian militants in Gaza supported by Iran to fire dozens of rockets into southern Israel, and threatened to retaliate wherever it chose.

The barrage of rockets, which began late Friday and continued into Saturday, triggered extensive retaliatory strikes by Israeli aircraft against Gaza that risked escalating into a wider conflict.

The new flare-up came hours after six Palestinians died in renewed clashes on the Gaza-Israel border even as the territory's Islamist rulers Hamas said Egypt was seeking to negotiate a return to calm.

"The rockets that were launched against Israel... we know that the orders, incentives were given from Damascus with the clear involvement of the Iranian Revolutionary Guards' Quds Force," army spokesman Lieutenant Colonel Jonathan Conricus said, referring to the Guards' foreign operations unit.

At least 39 rockets have been fired at southern Israel by the Islamic Jihad group since late Friday, with 17 of them intercepted by air defences and the rest hitting open ground, the army said.

Israeli aircraft carried out extensive retaliatory strikes, targeting approximately 90 sites belonging to the territory's Islamist rulers Hamas.

Conricus said that Israel held Hamas responsible for the fire, even though it was carried out by Islamic Jihad at the behest of Syria and its ally Iran.

"We hold Hamas responsible for everything coming from Gaza," he said. Conricus said Israel would also retaliate against the Syrian government and Iran's Quds Force, and would choose where.

"Part of the address by which we will deal with this fire is also in Damascus and the Quds Force," he said. "Our response is not limited geographically."
