According to an Israeli army statement, cross-border strikes were carried out by the army on Thursday after two rockets were fired from southern Lebanon towards Israel. Smoke was reported rising from the Lebanese border.
The incident comes after Israel this week targeted the Jenin camp, a Palestinian militant stronghold in the occupied West Bank. Israeli-Arab tensions have increased as Israel has carried out one of its biggest military offensives in years.
Three security sources in Lebanon said two rockets were fired at Israel, one landing on Lebanese territory and the second in a disputed area on the border.
The Israeli military initially said there were no signs of any unusual incidents on its side of the border, but said a shell exploded. No damage was reported.
Lebanon's state news agency NNA reported that more than 15 shells fell on the villages of Kfarchouba and Halta in the Israeli attack.
No one claimed responsibility for the rocket fire and there was no immediate comment from the Lebanese army or the United Nations peacekeeping force in southern Lebanon (UNIFIL).
