Israeli aircraft struck what its military said were rocket launch sites in south Lebanon early on Thursday in response to earlier projectile fire towards Israel from Lebanese territory.
Two rockets launched from Lebanon on Wednesday struck Israel, which responded with artillery fire amid heightened regional tensions over an alleged Iranian attack on an oil tanker in the Gulf last week.
There was no claim of responsibility for the rocket strike, launched from an area of south Lebanon under the sway of Iranian-backed Hezbollah guerrillas. There were no casualties.
In a further response to the rocket fire, the Israeli military said on Thursday that its "fighter jets struck the launch sites and infrastructure used for terror in Lebanon from which the rockets were launched."
