Washington (CNN) - House Speaker John Boehner Wednesday called the alleged Iranian terror plot to assassinate the Saudi ambassador to the United States on American soil "a serious breach of international behavior."
Boehner condemned the plan that U.S. government officials described Tuesday and called on the Obama administration to respond.
"I would hope that our administration would hold the Iranian government - hold their feet to the fire over the actions that, that have been alleged in this complaint," Boehner told reporters on Capitol Hill.
But when pressed on what specific actions the U.S. should take, Boehner declined to answer, saying only of those said to be responsible, "I'm hopeful that the administration will hold them accountable for their actions."
Earlier Wednesday Vice President Joe Biden said on the CBS Early Show that U.S. response could move beyond diplomatic sanctions, but said "we're not going there yet."
Biden stressed that the U.S. was reaching out to other nations to decide on the next steps.
"We are going to be working with the rest of the international community to decide what steps to take next. It's critically important that we unite the world in the isolation of and dealing with the Iranians."
