A key Hezbollah commander and members of his chain of command were killed in an Israeli strike in Beirut on Friday, according to the Israel Defense Forces, as tensions continue to rise along the Israel-Lebanon border.

At least nine people, including a key Hezbollah member, were killed in an Israeli strike on southern Beirut Friday.

Ibrahim Aqil, a senior member of Hezbollah and the target of the strike in southern Beirut, was killed, according to the Israeli army. Top operatives and the chain of command of the Raduan unit were also killed in the strike, according to the Israel Defense Forces.

Aqil and the commanders who were killed were allegedly planning to occupy Galilee, in what Israel claimed would have been similar to Hamas' Oct. 7 attack, IDF spokesman Daniel Hagari said in a statement.

Delta Air Lines has paused all flights between New York's John F. Kennedy International Airport and Tel Aviv, Israel, through Dec. 31 due to the "ongoing conflict in the region," the airline said in a release Thursday.

"Customers impacted by the schedule change will receive notifications via the Fly Delta app and contact information listed in their reservation as these cancellations are processed in Delta’s system," Delta said in a statement.

Travelers can still book seats on Delta partner airlines Air France and EL AL Israel Airlines through Delta's website.

Germany is being selective with what arms it is sending to Israel in light of rising tensions with Hezbollah and Hamas.

“There is no ban on licenses for arms exports to Israel and there will be no ban. The Federal Government decides on the granting of licenses for arms exports on a case-by-case basis and in the light of the respective situation after careful examination, taking into account foreign and security policy considerations in accordance with legal and political requirements,” the German Federal Ministry for Economic Affairs and Climate Protection said in a statement.

“In doing so, the Federal Government takes into account compliance with international humanitarian law. In this case-by-case assessment, the current situation is always taken into account, including the attacks on Israel by Hamas and Hezbollah as well as the course of the operation in Gaza,” the ministry said.

At least 37 people -- including two children -- were killed across the country by exploding communication devices on Tuesday and Wednesday, Lebanese Health Minister Firass Al-Abyad said in a press conference Thursday. About 3,000 people were injured, he said.

"It is certain that what happened in terms of aggression is considered a war crime, as the majority of the injuries were recorded in civilian areas and not in the battlefield, and the government is doing its duty and has called for a meeting of the U.N. Security Council, and human rights organizations are doing their duty on this issue,” Al-Abyad said.

Hezbollah said 20 of its members were killed in Wednesday's walkie-talkie explosions. Another 11 were killed in Tuesday's pager explosions in Lebanon and Syria, bringing the overall death toll for the group to 31.

Israel was responsible for Tuesday's explosions, a source confirmed to ABC News, in which pagers detonated across Beirut and southern Lebanon. Walkie-talkies exploded on Wednesday.
