The American Israel Public Affairs Committee — a pro-Israel group that lobbies both Congress and the White House — said Tuesday it was "deeply concerned" about the Iran nuclear deal announced by President Obama.

"During these negotiations, we outlined five critical requirements for a good deal," AIPAC said in a statement. "We are deeply concerned based on initial reports that this proposed agreement may not meet these requirements, and thereby would fail to block Iran's path to a nuclear weapon and would further entrench and empower the leading state sponsor of terror."

AIPAC, which has "consistently supported diplomatic efforts" to ensure Iran does not develop nuclear weapons, said it "appreciates the administration's efforts and hard work" in the negotiations. The group also said it hopes Congress carefully reviews the agreement "to ensure that Iran is verifiably prevented from obtaining a nuclear weapon."

A long-term comprehensive nuclear deal was announced Tuesday after a final wave of 18 days of talks by negotiators from Iran, the U.S., Germany, China, Britain and France. Congress now has 60 days to approve the deal once it is officially delivered to members.
