Hezbollah warns Israel against targeting Palestinian militants in Lebanon

The head of Lebanon's powerful armed movement Hezbollah, Sayyed Hassan Nasrallah, warned on Tuesday against any Israeli attempts to expand their targeting of Palestinian militants to Lebanon.

"Any attack on any human being will not go unpunished or unanswered," Nasrallah said in a televised address marking Ashura, a melancholic commemoration for Shi'ite Muslims of the killing the Prophet Mohammad's grandson Hussein.

The comments came after a flare-up in violence between Israel and the Islamic Jihad movement in the Gaza strip, prompted by Israel's arrest of a senior Islamic Jihad leader earlier this month.

On Saturday, Israeli defence minister Benny Gantz hinted at the possible targeting of Islamic Jihad officials abroad, who he said could be seen in "restaurants and hotels in Tehran, Syria and Lebanon".

"They too will have to pay the price," Gantz said.

On Monday, a day after a truce brokered by Egypt ended the Gaza violence, he said Israel could carry out "pre-emptive strikes" abroad.

"In the future too, if necessary, we will deliver a pre-emptive strike in order to defend Israel's citizens, sovereignty and infrastructure and this is true for all fronts, from Teheran to Khan Younis," he said.

Iran-backed Hezbollah is vehemently opposed to Israel and tensions between the two have been escalating in recent months over a disputed maritime border between Lebanon and Israel.
