WASHINGTON (AP) -- President Barack Obama is using a Friday webcast to try to allay concerns from Jewish communities about the nuclear agreement with Iran.

Obama will deliver remarks about the agreement and take questions from participants. The webcast is being organized by two major Jewish organizations that have held similar events with Israeli Prime Minister Benjamin Netanyahu and Energy Secretary Ernest Moniz.

The Israeli government adamantly opposes the deal signed by the U.S., Iran and five world powers. The agreement seeks to keep Iran from building a nuclear bomb in exchange for international sanctions relief. Critics say the agreement makes too many concessions and could eventually allow for a nuclear-armed Iran.

The president counters that the agreement contains the most comprehensive inspection and verification regime ever negotiated to monitor a nuclear program.
