NEW YORK – The White House reiterated Wednesday that the United States was not involved in a series of attacks that saw booby-trapped devices explode this week in Lebanon.

“What I can tell you is we were not involved in yesterday’s incidents or today’s in any way, and I don’t have anything more to share,” National Security Council spokesperson John Kirby told reporters during a White House press briefing.

Pressed in a follow-up exchange with another reporter, Kirby wouldn’t say if Defense Secretary Lloyd Austin received a heads up on Wednesday’s attack, which saw scores of walkie-talkies explode across Lebanon, during a Tuesday call with Israeli Defense Minister Yoav Gallant. Kirby repeatedly declined to confirm on the record that Israel was behind the electronics attacks, telling reporters, “I’m not going to get into intelligence assessment, estimates and assessments from here.

CNN has reported that Tuesday’s pager explosion attacks, which have heightened tensions in a region already on edge, was a joint operation between Israel’s intelligence service, the Mossad, and the Israeli military. The Lebanese government condemned the attack as “criminal Israeli aggression.”

But Kirby acknowledged the administration is concerned over the prospect of tensions escalating in the region, saying the US does not believe “additional military operations” are the solution. He pointed to diplomacy instead.

United Nations Human Rights Chief Volker Türk has condemned the pager blasts in Lebanon on Tuesday that killed at least 12 people and injured around 2,800. Türk called the attacks a violation of international humanitarian law and called for an “independent, thorough and transparent investigation.” CNN has learned that the Israeli military and intelligence service were behind Tuesday’s attack, but Israeli officials have not publicly commented on it, or on Wednesday’s walkie-talkie explosions.  Türk also did not comment on Wednesday’s walk-talkie blasts, and his comments were only in reference to the Tuesday pager blasts.
