BEIRUT (Reuters) - Lebanese Hezbollah militants killed and wounded a number of Israeli soldiers in a "big operation" on Wednesday targeting an Israeli military convoy in a frontier area, a Lebanese political source said.

The attack in the Israeli-occupied Shebaa Farms area was in response to an Israeli rocket attack in Syria, the source, who is familiar with details of the operation, said.
