(BBC News) The Israel Defence Forces (IDF) has said it is striking Hezbollah targets in Lebanon.
It has not given further information.
Lebanese Al Mayadeen TV reported that Israeli air strikes targeted two villages in southern Lebanon in the early hours of Thursday.
The missiles were fired at Kafr Shuba and near Odaisseh, the channel added.
Hezbollah said it carried out attacks on Israeli military posts along the Israel-Lebanon border on Wednesday.
Hezbollah – like Hamas – has been designated a terrorist organization by the UK, U.S., and other countries.
Backed by Iran, it has a strong military and political presence in Lebanon, and wields considerable power in a country without a functioning government or president.
In 2006, it fought a war with Israel in which 1,200 people died.
