Israel-Gaza live updates: Death toll rises from pager, walkie-talkie explosions

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.

The Israel Defense Forces said it is carrying out strikes in Lebanon to "degrade Hezbollah’s terrorist capabilities and infrastructure," according to a statement.

"The Hezbollah terrorist organization has turned southern Lebanon into a combat zone. For decades, Hezbollah has weaponized civilian homes, dug tunnels beneath them, and used civilians as human shields. The IDF is operating to bring security to northern Israel in order to enable the return of residents to their homes, as well as to achieve of all of the war goals," the IDF said in a statement.

The strikes come after two consecutive days of explosions of pagers and walkie-talkie devices in Lebanon, which left at least 37 people dead.
