British Foreign Secretary David Lammy warned on Wednesday that countries "must not waver" as they work towards ceasefires in Gaza and Lebanon, as he visited two regional allies.

Lammy, who will hold talks with leaders in Bahrain and Jordan and meet UK armed forces personnel currently stationed in the Middle East, called the situation there "incredibly dangerous."

The Israeli military said it intercepted two projectiles fired from Lebanon on Wednesday shortly after air raid sirens blared in and around the coastal town of Caesarea, south of Haifa.

Six were injured in the rocket attack.

Hezbollah and Israeli forces exchanged fire along the Lebanon-Israel border on Wednesday, ahead of expected talks between Israeli Prime Minister Benjamin Netanyahu and U.S. President Joe Biden.

Hezbollah said Wednesday that its fighters repelled more than three Israeli army attempts to infiltrate southern Lebanon, as Israel intensifies its ground offensive against the Lebanese, Iran-backed group.

Doha launched an "air bridge" to transport medical supplies and food aid to Lebanon, a Qatari minister said in Beirut on Tuesday, more than two weeks into intense Israeli strikes on the country.

"Today we launched the air bridge with consecutive planes carrying food, shelter materials and medical supplies," said Qatar's Minister of State for International Cooperation Lolwah Al-Khater from a public hospital in Beirut.

Beirut has received "assurances" that Israel will not target the country's only international airport, Lebanon's transport minister told AFP, but said those fell short of guarantees.

Since September 23, Israel has launched an intense air campaign mainly targeting Hezbollah strongholds in Lebanon including Beirut's southern suburbs, adjacent to the airport.

Israeli Prime Minister Benjamin Netanyahu confirmed Tuesday that Israel assassinated the projected new Hezbollah leader Sayyed Hashem Safieddine, who was targeted in a massive airstrike in Beirut's southern suburbs on Thursday, claiming also that Israel has killed Safieddine’s replacement, without saying who this would be.

In an English-language video message to the Lebanese public, Netanyahu said that Israel has “degraded Hezbollah’s capabilities; we took out thousands of terrorists, including [longtime Hezbollah leader Sayyed Hassan] Nasrallah himself, and Nasrallah’s replacement, and the replacement of his replacement.”

The Israeli army said 30 soldiers have been wounded in the past twenty four hours on the Lebanese border as it launched targeted raids against Hezbollah, expanding its ground operations along the country's coastline after deploying more troops.

Hezbollah said it targeted troops in Labouneh near al-Naqoura, where U.N. peacekeepers are headquartered.

Sheikh Naim Qassem has been the acting head of Hezbollah since its longtime leader Sayyed Hassan Nasrallah was killed as part of an Israeli offensive that has taken out many of the group's senior officials.

Qassem made a defiant televised speech Tuesday, claiming that the group's military capabilities are intact and Israelis will only suffer further as fighting continues.

Israel's Defense Minister Yoav Gallant on Tuesday said Hezbollah had been "battered and broken" following continuous strikes against the group and the killing of its leader Sayyed Hassan Nasrallah.

During a briefing with the northern command, Gallant said Hezbollah "is a battered and broken organization, without significant command and fire capabilities, with a disintegrated leadership following the elimination of Hassan Nasrallah". Earlier on Tuesday the military said about 85 projectiles were fired from Lebanon at northern Israel.

The Biden administration has in recent weeks grown “increasingly distrustful” of what the Israeli government says about its military and diplomatic plans in the multi-front war it is fighting, four U.S. officials told U.S. news portal Axios.
