Israeli warplanes blasted runways at the main army air base in eastern Lebanon near Syria's border Thursday, police said, an attack that could draw the Lebanese army into Israel's war with Hezbollah guerrillas.
Earlier, Israeli warplanes struck the runways of Beirut's international airport as part of a campaign against Hezbollah, which attacked Israeli border positions Wednesday and captured two soldiers.

Light, sweet crude for August delivery shot up $1.35 to $76.30 a barrel on the New York Mercantile Exchange, surpassing the previous intraday high of $75.78 set last Friday.

"With little prospect of any good news on Nigeria, Iran and global demand any time soon, the risks remain on the upside and the prospect of a move to, and through, $80 per barrel must be very real, very soon," said Paul J.

Heating oil rose more than 3 cents to $2.0527 a gallon; gasoline rose more than 2 cents to $2.2825 a gallon, and natural gas futures gained 10 cents to $5.880 per 1,000 cubic feet.
In the United States, the national gas price average now hovers near $3 a gallon, CBS News correspondent Susan McGinnis reports, and some experts are saying $3.50 a gallon is inevitable or even $4 may be on the horizon. McGinnis notes that while gas prices have yet to cut into Americans' driving plans in any major way, this could change if prices rise to $4 at the pump.
In Nigeria, officials said twin explosions hit oil installations belonging to oil company Agip, a unit of Italy's Eni SpA, in the volatile southeastern delta region. Officials suspected sabotage in the explosions Wednesday along two pipelines in Baleysa state.
