(RFE/RL) -- Israel stepped up its massive air strikes on Beirut's southern suburbs in its drive to wipe out Hezbollah's capabilities and leadership, even as the world awaits with trepidation the October 7 anniversary of the bloody attack on Israel by Hamas -- which, like Hezbollah, is a U.S.-designated terror group with ties to Iran.
Meanwhile, Tehran said it had lifted “all flight restrictions” after earlier announcing it was closing Iranian airports as of 9 p.m. on October 6 until 6 a.m. on October 7, citing "operational restrictions," at a time when Israel is weighing options for its response to Iran's recent massive missile strike on its territory.
State media said the restrictions were lifted “after ensuring favorable and safe conditions.”
Israeli Defense Minister Yoav Gallant on October 6 threatened Iran that it might eventually find itself looking like Beirut or Gaza -- which has also been battered over the past year -- if Tehran attempts to further harm Israel.
"The Iranians did not touch the air force's capabilities. No aircraft were damaged, no squadron was taken out of order," Gallant said in reference to the Iranian missile strike, which caused few injuries and slight damage to two air force bases.
"Whoever thinks that a mere attempt to harm us will deter us from taking action should take a look at [Israel’s operations] in Gaza and Beirut,” where Israel is battling fighters of Hamas, which has been deemed a terrorist organization by the United States and EU.
Israel earlier said conducted a series of “targeted strikes” on “weapons storage facilities” and infrastructure sites that belong to Iran-backed Hezbollah.
Hezbollah has been designated by the United States as a terror group, while the European Union has blacklisted its armed wing but not its political unit, which holds seats in the Lebanese parliament.
Lebanon's official National News Agency said Hezbollah's stronghold in the area was hit by more than 30 strikes. A petrol station and a medical supplies warehouse were hit by the air raids.
Video footage showed huge flames and plumes of smoke billowing into the night sky, as residents fled their homes in panic with explosions echoing in the background.
Many observers said the attacks were the strongest yet of Israel's recent air strikes.
"Last night was the most violence of all the previous nights," Hanan Abdullah, a resident of the Burj al-Barajneh area in Beirut's southern suburbs, told Reuters.
"Buildings were shaking around us and at first I thought it was an earthquake. There were dozens of strikes -- we couldn't count them all -- and the sounds were deafening,"
Israel has bombed Beirut suburbs for days, killing Hezbollah leader Sayyed Hassan Nasrallah and possibly his potential successor, Hashem Safieddine.
Security sources have said Safieddine had been out of contact since October 4, after an Israeli air strike near Beirut’s international airport that was reported to have targeted him. Hezbollah has not commented on Safieddine.
Israel says Nasrallah was killed in a strike on the group's central command headquarters in Beirut on September 27.
Two senior Iranian security officials told Reuters on October 6 that Ismail Qaani, commander of the Quds Force -- the overseas arm of Iran's Islamic Revolutionary Guards Corps (IRGC) -- also had not been heard from in recent days since traveling to Lebanon.
Senior Hezbollah member Mahmoud Qmati, when asked about Qaani's whereabouts, told Reuters: "I have no information. We are also searching for the truth of this matter.
Statements on October 6 out of the United States -- Tel Aviv's most important ally -- indicated some frustrations with the scope of Israel's military action.
"Military pressure can at times enable diplomacy. Of course, military pressure can also lead to miscalculation. It can lead to unintended consequences," a U.S. State Department spokesperson said in statement.
The spokesperson said Washington supported Israeli actions in going after extremist elements but added that U.S. leaders but did not approve of the targeting of civilian infrastructure.
"Every civilian casualty is one too many," the spokesperson said.
Israel said on October 5 that its forces had killed 440 Hezbollah fighters in ground operations in southern Lebanon and destroyed 2,000 Hezbollah targets. Nine Israeli soldiers had been killed in southern Lebanon so far, the authorities said.
According to the Lebanese Health Ministry, nearly 2,000 people have been killed in Lebanon in the latest conflict, most of them since September 23.
Israel says the attacks on Hezbollah are aimed at enabling the safe return of tens of thousands of citizens to homes in northern Israel, bombarded by the group since last October.
The Israeli forces were on high alert ahead of the first anniversary of an attack on October 7 last year, which sparked the war and was carried out by Hamas.
According to Israel tallies, some 1,200 people were killed and about 250 taken hostage in the unprecedented Hamas attack on southern Israel.
Israeli police on October 6 said several people had been injured in a suspected shooting attack in Beersheba, a city in southern Israel. One attacker was killed, the ambulance service said.
Separately, health officials in Hamas-run Gaza reported on October 6 that at least 41,870 Palestinians have been killed in the territory in the yearlong war between Israel and Palestinian militants.
Palestinian officials said that an Israeli strike on a mosque in Gaza early on October 6 killed at least 19 people who were sheltering after being displaced from their homes near the town of Deir al-Bala.
The Israeli military said the strike was targeting militants. The reports could not immediately be confirmed, but the Associated Press said one of its journalists counted the bodies at the Al-Aqsa Martyrs Hospital morgue.
AP also reported that hospital records showed that the fatalities from the mosque strike were all men.
Israel said its forces on October 6 surrounded the Jabaliya area of northern Gaza in response to indications that Hamas was rebuilding “its operational capabilities in the area.”
Israel is also considering a retaliatory strike on Iran, which fired at least 180 ballistic missiles at Israel on October 1.
Iranian Oil Minister Mohsen Paknejad visited Kharg island on October 6, amid concerns that Israel could target Iran's largest oil terminal there.
"The Islamic Revolutionary Guard Corps [IRGC] Navy plays an important role in the security of oil and gas facilities," Paknejad was quoted as saying at the facility, from which around 90 percent of Iranian oil exports are shipped.
In Syria, state media and local rights monitors said an Israeli air strike targeted three cars in the city of Homs, although details remained sketchy.
Israeli forces have for years been striking Iran-linked targets in Syria and have intensified such actions since the October 7 attacks.
