Northern Israel was hit by two Katyusha rockets fired from the Lebanon Monday night, according an Israeli police spokesman.

This attack comes a day before the arrival of U.S. President George W. Bush in Israel in order to support the peace talks between Israel and the Palestinians.

The attack occurred around 2 a.m. and it hit the road which leads in the town of Shlomi, which is located about a few miles from the border with Lebanon, according to Washington Post.

According to police spokesman Mickey Rosenfeld, shrapnel hit the wall of a house. No one was injured.

Still, Defense Minister Ehud Barak called the accident a “grave” on

He said: "We will learn what happened together with the army officers, we'll think and decide how to act," AFP reports.

The Hezbollah militia declared that they had no information regarding this matter. The Hezbollah, based in Lebanon, carried a 34-day war with Israel in the summer 2006. It fired nearly 4,000 rockets at Israeli towns, killing 40 civilians and 119 soldiers. Another 1,000 Lebanese died in the conflict.

This was the first time in six months when the northern Israel was attacked by Katyusha rockets. In June 2007 a pair of rockets hit the town of Kiryat Shemona. No one was injured.

The accident is being investigated by a UN peacekeeping force (UNIFIL), which is monitoring the ceasefire between Israel and Lebanon.

Spokeswoman Yasmina Buziane said: “UNIFIL is in the process of ascertaining the facts. We have our team on the ground. In the meantime, we cannot confirm or deny this report.”

On Tuesday Israeli army released a Lebanese shepherd into UNIFIL custody. They’ve arrested the man on Monday for crossing into Israel, according to police.

An Al-Qaeda inspired militia leader said that the 15-week battle with the Lebanese troops last year was only the beginning.

The audio message said: "Our message to the crusaders is to expect the worst. This battle was only the beginning and we will prevail.”
