The head of Lebanon’s powerful Hezbollah has said that his armed group had used new types of weapons and struck new targets in Israel in recent days, pledging that the front in the south against its sworn enemy would remain active.

According to Reuters, it was Sayyed Hassan Nasrallah’s second speech since the conflict between Israel and Hamas began in October.

Nasrallah said on Saturday there had been “an upgrade” in Hezbollah’s operations along its front with Israel. “There has been a quantitative improvement in the number of operations, the size and the number of targets, as well as an increase in the type of weapons,” he said in a televised address.

Nasrallah said the group had also struck the northern Israeli town of Kiryat Shmona for the first time in retaliation for the killing of three girls and their grandmother earlier this month. “This front will remain active,” he pledged.
