Israeli warplanes fired missiles at a suspected guerrilla hideout in south Lebanon on Wednesday, shortly after Hezbollah gunners fired on Israeli jets, security officials said.
The Lebanese officials in southern Lebanon said two Israeli fighter jets fired at a valley near the village of Zibqine, southeast of the port city of Tyre. Hezbollah officials in south Lebanon said at least four air-to-surface missiles were launched in the afternoon attack.
Black smoke billowed from the area. There was no immediate word on casualties.
The Israeli airstrike, the first in south Lebanon since March, came two hours after Hezbollah anti-aircraft guns fired on Israeli warplanes that flew over the region.
Earlier Wednesday, shells from Hezbollah anti-aircraft fire landed on an Israeli community along the border, the Israeli army said. No one was hurt.
The last Israeli airstrike in Lebanon was March 23, when Israeli helicopter gunships fired on gunmen in the south, killing two and wounding one. The gunmen were preparing to launch rockets into Israel, according to Lebanese security officials.
The region has been relatively quiet since Israel withdrew its forces from southern Lebanon in 2000 after an 18-year occupation.
Hezbollah, which waged a guerrilla war against the Israelis, has repeatedly clashed with Israeli soldiers in the disputed Chebaa Farms area near the border. Israel has launched airstrikes and artillery attacks against guerrillas positions.
