Hezbollah fired another barrage of rockets into Israel on Tuesday, as Hezbollah deputy chief Naim Qassem vowed to keep up pressure that has forced tens of thousands of Israelis from their homes near the Lebanese border.

Dozens of rockets fired by Hezbollah were aimed as far south as Haifa, and the Israeli government warned residents north of the coastal city to limit activities, prompting the closure of more schools. The Israeli military said Hezbollah launched more than 170 rockets across the border.

Hezbollah deputy chief Sheikh Naim Qassem on Tuesday said the group's military capabilities remained "fine" despite weeks of heavy Israeli airstrikes.

"You see that our daily accomplishments are great. Hundreds of rockets and dozens of aircraft (drones), a great number of (Israeli) settlements and cities have come under rocket fire... I would like to reassure you that our capabilities are fine," Qassem said in a televised address.

Hezbollah has ordered its fighters not to attack Israeli troops who recently moved behind a U.N. peacekeeping position near a Lebanese border village.

The statement came a day after UNIFIL had warned Israel's operations near their position at Maroun al-Ras was "extremely dangerous" and compromised their safety, adding it had repeatedly informed Israel of their concerns.

The United States has warned Israel not to attack Beirut airport or the roads leading to it, as the Israeli army carried out intensive strikes on the Lebanese capital's southern suburbs.

"We think it's very important that not only the airport be open, but that the roads to the airport be open, so that American citizens who want to leave can get out, but also citizens of other countries," State Department spokesman Matthew Miller told reporters.

The Israeli military said it killed a senior Hezbollah commander in a strike on south Beirut.

The military said Tuesday that it killed Suhail Husseini, who it said was responsible for overseeing logistics, budget and management of the militant group.

U.N. Special Coordinator for Lebanon Jeanine Hennis-Plasschaert and UNIFIL Head of Mission and Force Commander Lt. Gen. Aroldo Lázaro have called for a “negotiated solution” to end the current conflict between Israel and Hezbollah.

Turkey is sending ships to evacuate around 2,000 of its citizens from Lebanon on Wednesday, the foreign ministry said.

Two Turkish navy ships will leave a port in southern Turkish province of Mersin for Beirut on Tuesday, the ministry said in a statement.

The Israeli military said on Tuesday it had launched targeted raids against Hezbollah in southwest Lebanon, expanding its ground operations along the country's coastline after deploying more troops.

"Yesterday (Monday), the 146th Division began limited, localized, targeted operational activities against Hezbollah terror targets and infrastructure in southwestern Lebanon," the military said in a statement on its Telegram channel.

A Lebanese security source said an Israeli strike hit Monday near the country's only airport in Beirut, close to Hezbollah's stronghold in the south of the capital.

"Israel conducted an air strike near the airport," the official said, requesting anonymity to discuss sensitive matters.

The French-U.S. proposal for a ceasefire to end fighting in Lebanon remains on the table, with parties continuing to work on it, French Foreign Minister Jean-Noel Barrot said Monday during a visit to Israel.

He said Israel’s security cannot be guaranteed with military force alone and will require a diplomatic solution.
