'In response to the blatant violation by the Hezbollah terrorist organization, the IDF has begun targeted strikes in southern Lebanon,' the military said.

'We are not easing off the gas. On the contrary, I have instructed to press harder,' Netanyahu said.

The high-profile elimination came against the backdrop of the largest Israeli strike wave since the start of Operation Roaring Lion.

Tanks were dispatched to the scene and opened fire shortly after the terrorists were identified.

The army described the terrorists’ activities as 'a clear violation' of security agreements between Israel and Lebanon.

'Those who attack our soldiers or violate agreements will pay the full price.'

The IDF said the operations were based on precise intelligence and aimed at preventing Hezbollah from strengthening its positions along the border.

'The president made it clear to Hamas that if they did not release all of the hostages, there would be hell to pay,' the White House press secretary said.

Jack Lew, the U.S. ambassador to Israel, said in a briefing there are 'indications' that Mohammed Deif is dead. 

An operation that included the Menashe Brigade and aircraft eliminated two terrorists in Jenin.
