The leader of Hezbollah, Hassan Nasrallah, warned the conflict with Israel has entered a "new phase."

Nasrallah spoke via videofeed at the funeral of Hezbollah commander Fouad Shukur, who was killed in an Israeli strike Tuesday in Beirut.

Israel said Shukur was behind a rocket attack days earlier that hit a soccer field in the Israeli-occupied Golan Heights, killing 12 children.

"Our response is coming," Nasrallah said during the funeral.

He also cryptically warned them that "the enemy and the one who is behind the enemy," presumably Israel's ally the United States, "will have to wait for our coming response."

The attack on Shukur has since been somewhat overshadowed by the death of Hamas leader Ismail Haniyeh in Tehran.

There areconcerns about a potential large, coordinated attack on Israel by Iran, Hezbollah, and other allied militias in the region.
