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.

Israeli police and the Shin Bet intelligence service foiled an alleged plot to kill Prime Minister Benjamin Netanhayu and other prominent individuals, according to details of an indictment released on Thursday.

Moti Maman, a 73-year-old Israeli businessman from the city of Ashkelon, is accused of twice smuggling himself into Iran via Turkey to meet with intelligence officials directing would-be plots from Tehran.

The discussions allegedly included potential plans to attack Netanyahu, Defense Minister Yoav Gallant, Shin Bet chief Ronen Bar and former Prime Minister Naftali Bennett, among others.

Police and Shin Bet said the alleged plots were intended as retaliation for the killing of Ismail Hanieyh in Tehran in July, which Iran blamed on Israel.

A joint police and Shin Bet statement also accused Maman of discussing the possibility of acting as a money courier for others in Israel, locating Russian and American elements for the elimination of Tehran's opponents in Europe and the U.S. and recruiting Mossad personnel as double agents.

"The Israeli citizen demanded an advance payment of $1 million dollars before performing any action," police and Shin Bet said. "Iranian agents refused his request and informed him they would contact him in the future."

Maman allegedly received around $558,000 -- paid in euros -- for attending the meetings with Iranian intelligence personnel.
