The Israeli military's spokesperson Ran Kochav said Monday the army will respond to any rocket attack initiated from Lebanon.
A rocket was launched late on Sunday towards the western Galilee and landed in an open field, causing no injuries or damage. Rocket alert siren was not activated.
Ran Kochav told Ynet that Israel has a number of potential responses in its arsenal should the attacks be renewed. "Some of the [responses] are immediate, and others are kept in secrecy."
Kochav said the IDF would not allow a continuation of rocket fire and will respond accordingly. "We are adamant that the next weeks remain perfectly quiet in the north. That is our mission," he said.
Israel will mark Holocaust Memorial Day on Wednesday, and on next week will mark Memorial Day for Israel's fallen soldiers as well as Independence Day.
Kochav said that no group has claimed responsibility for the rocket launch, but estimated that a Palestinian faction operating in southern Lebanon was behind the fire that was a show of solidarity with the protests at the Al Aqsa Mosque compound in Jerusalem in recent weeks.
He conceded that Hamas operatives across the northern border, numbering in the hundreds, may have launched the rocket. "There is clearly a connection between the southern and northern fronts," he said.
"We are not all that interested in who did the actual firing. We are more focused on protecting the country from on all fronts from the Islamic Jihad, rogue factions, Hezbollah or anyone else, our mission is to protect Israeli citizens and we are prepared for any scenario," he said.
Kochav said the IDF will embark on a military campaign if that will be needed.
"We will not hesitate," he said. "I want to make clear to Israelis and to our enemies in Gaza, Lebanon or elsewhere that we will not allow rocket fire," he said.
Kochav said Israel saw the Gaza ruling Hamas group responsible for all attacks from the Strip.
"We see Hamas also influencing events on the West Bank, on Temple Mount and in south Lebanon," he said.
