Biden Cites Hezbollah 'Reign Of Terror,' While UN Chief Expresses 'Grave Concern' At Nasrallah's Death

U.S. President Joe Biden, in his first comments since the Israeli killing of the leader of the Iran-backed Hezbollah militant group in Lebanon, said the death of Hassan Nasrallah helped bring a "measure of justice" to the group's many victims over a four-year "reign of terror," while Tehran and many of its allies condemned the Israeli attacks.

In a statement released by the White House on September 28, Biden said Nasrallah's "death from an Israeli air strike is a measure of justice for his many victims, including thousands of Americans, Israelis, and Lebanese civilians."

"The United States fully supports Israel's right to defend itself against Hezbollah, Hamas, the Huthis, and any other Iranian-supported terrorist groups. Just yesterday, I directed my secretary of defense to further enhance the defense posture of U.S. military forces in the Middle East region to deter aggression and reduce the risk of a broader regional war."

Hezbollah and Hamas have been designated as terrorist organizations by the United States.

"Ultimately, our aim is to de-escalate the ongoing conflicts in both Gaza and Lebanon through diplomatic means," Biden said, referring to the war between Israeli forces and Hamas militants in the Gaza Strip brought on by Hamas fighters' October 7 deadly assaults inside Israel.

Separately, Vice President Kamala Harris, who is the Democratic candidate to compete against Republican Donald Trump for the presidency in the November 5 election, said that diplomacy remained the "best path forward to protect civilians and achieve lasting stability" in the region.

"Hassan Nasrallah was a terrorist with American blood on his hands," she said, adding that "I have an unwavering commitment to the security of Israel."

"I will always support Israel's right to defend itself against Iran and Iran-backed terrorist groups such as Hezbollah, Hamas, and the Huthis."

United Nations Secretary-General Antonio Guterres, meanwhile, said he was "gravely concerned" by the "dramatic escalation" seen in Lebanon over the past 24 hours.

UN spokesman Stephane Dujarric added that Guterres believes “this cycle of violence must stop now. The people of Lebanon, the people of Israel, as well as the wider region, cannot afford an all-out war.”

Moscow condemned the killing of Nasrallah, with the Foreign Ministry labeling it "yet another political assassination."

"This forceful action is fraught with even greater dramatic consequences for Lebanon and the entire Middle East," it said.
