Israeli troops are pursuing operations inside the northern Gaza Strip, a day after authorities said they would extend ground activities in the Palestinian enclave, army radio reported. Israeli fighter jets struck about 150 underground targets in Gaza overnight.

Iran’s Foreign Minister Hossein Amirabdollahian warned that new fronts would open against the US if it continues its unequivocal support for Israel. Iran began two days of exercises on Friday in its central Isfahan province involving helicopters, missiles, drones and artillery.

Israel said that it’s expanding military activity in Gaza, as the strip lost internet and telephone service and international agencies lost contact with staff there. The United Nations General Assembly approved a resolution calling for an “immediate, durable and sustained humanitarian truce” in the conflict.

Israel Strikes Underground Targets in Gaza (8:19 a.m.)

Iran Begins Military Exercises (8:00 a.m.)

Israel Says It Killed Head of Hamas’s Aerial Array (7:38 a.m.)

US Says No Casualties in Strikes on Iranian Targets (1:45 a.m.)

The Pentagon said US attacks on Iranian targets Thursday night were focused on storage facilities for weapons and ammunition used by Iran’s Islamic Revolutionary Guard Corps and resulted in no casualties.

“These narrowly-tailored strikes in self-defense were intended solely to protect and defend US personnel in Iraq and Syria,” Brigadier General Pat Ryder, a Defense Department spokesman, said in a statement. “They are separate and distinct from the ongoing conflict between Israel and Hamas, and do not constitute a shift in the U.S. approach to the Israel-Hamas conflict.” Ryder said that coalition forces had been attacked 14 times in Iraq and six times in Syria by rockets and drones. Most of the attacks failed to reach their targets, he added.

Iran Warns of ‘New Fronts’ Against the US (12:35 a.m,)

Iran’s foreign minister warned that new fronts would open against the US if it keeps up unequivocal support for Israel, and said Prime Minister Benjamin Netanyahu’s government would regret its actions if it proceeds with a full-scale invasion.

Foreign Minister Hossein Amirabdollahian declined to detail the consequences Iran might have in store. But his comments in an interview signaled an escalation in the rhetoric between Washington and Tehran after a series of attacks on US forces in Syria and Iraq fanned concerns that the Israel-Hamas conflict would turn into a wider regional war.

Iran Denies Directing Groups That Attacked US Forces (12:10 a.m.)

Iran’s foreign minister said groups attacking US forces in Syria and Iraq are acting independently, and haven’t received orders or instructions from Tehran. “They’re not receiving any orders from us, any instructions,” Foreign Minister Hossein Amirabdollahian said in an interview with Bloomberg Television. “The American side claims that these are linked to Iran. These groups decide for themselves independently.”

Amirabdollahian spoke less than a day after the US said that it had conducted military strikes on two Syrian facilities linked to Iran’s Islamic Revolutionary Guard Corps that had been used for attacks against US troops in the region. US officials have said they don’t have evidence that Iran explicitly ordered the attacks, but they hold Iran responsible because it supports the groups.
