Israeli border post attacked

South Lebanon comes under Israeli fire earlier this week

JERUSALEM (CNN) -- Guerrillas attempted to infiltrate an Israeli army position along the border with Lebanon Wednesday but were repelled, the Israel Defense Forces said.

The attempted infiltration came after guerrillas fired mortars and rockets at Israeli positions near the Lebanese border Wednesday and the IDF responded with tank fire, artillery, and fighter jets.

No Israeli casualties were reported, but Israeli positions on Mount Hermon, Har Dov and in the northern Golan Heights reported taking fire from suspected Hezbollah guerrillas.

The attack marked the 12th day Israeli forces along the Lebanese border have come under fire from Lebanon.

On Monday, the IDF said it was sending more forces to its northern border with Lebanon in an attempt to control cross-border attacks from Hezbollah militants.

The recruitment of more Israeli reserve units is due to "the worsening characteristic of activities initiated by the Hezbollah and the possible deterioration in the sector," said the IDF statement, released on Monday.

A spokesman for the IDF office would not disclose how many troops were being called up but said their recruitment would be immediate.

In Lebanon on Sunday, a U.N. envoy urged restraint after Israel launched heavy air attacks against suspected Hezbollah hideouts in southern Lebanon in response to artillery and mortar fire against Israeli military positions near the Golan Heights.

Cheney warns Syria

U.S. Vice President Dick Cheney warned Syrian President Bashar al-Assad in a telephone call Monday that Israel would retaliate if fired upon by Syrian-backed forces in Lebanon, administration officials said Wednesday.

Syria and Iran back guerrillas belonging to Hezbollah, which supports the Palestinians' uprising against Israel and were instrumental in forcing Israel to withdraw from Lebanon.

Cheney warned that the recent confrontations on the Israel-Lebanon border could further destabilize the region and undermine new U.S. efforts to negotiate a cease-fire between Israelis and Palestinians, the officials said.

"The vice president carried the message of the high U.S. interest in there being quiet on the border between Israel and Lebanon," one official said. "He wasn't warning that there would be U.S. retaliation but was making it clear Israel was not going to stand for (cross-border attacks)."
