Al Qlayleh, Lebanon: shelled southern Lebanon on Saturday after a rocket slammed into its territory , sources on both sides said.

Israeli rescue services said three people were injured when the rocket struck near the town of Maalot in the western Galilee region, triggering an immediate response from Israel.

Lebanese Prime Minister Fouad Siniora denounced the violence. The Hezbollah group denied any involvement. The militant group has a large rocket arsenal but is not believed to have used them against Israel since their 2006 war.

Lebanese security said the rockets were fired from the Mansouri and Al Qulaila areas near the coastal town of Naqoura. Initially there were reports that the rockets had fallen short of their target, landing in empty fields inside Lebanese territory close to the border.

But a senior Lebanese official later said one rocket appeared to have landed in Israel.

An Israeli army spokesman said the military responded to the firing. He did not elaborate.

Israeli paramedics in Jerusalem said one rocket landed in northern Israel, lightly injuring three people who were evacuated to a hospital in the nearby coastal town of Nahariya.

The Lebanese officials said Israel responded by firing at least six shells on villages in the vicinity of the area where the rockets had been launched. They spoke on condition of anonymity in line with military regulations.

Rockets from Lebanon have been fired into Israel on two occasions during Israel's Gaza offensive.

The firing came a day after the Israeli president chose hard-line Likud leader Benjamin Netanyahu to form a new Israeli government.

Meanwhile, the Palestinian Authority called on a Likud-led Israeli government to recognise previous peace agreements on the occupied territories, as Benjamin Netanyahu appeared set to become Israeli prime minister.

In his first reaction, Palestinian Authority President Mahmoud Abbas said the Palestinian leadership "will not deal with the new Israeli government if it doesn't show commitments towards peace."
