Israeli President Peres says best to keep options open on Iran after visit to World Court

Israeli President Shimon Peres says that "all options" should be kept open in forcing Iran to give up its nuclear program, which Iran says is for peaceful purposes but Israel believes is aimed at building nuclear arms.

Peres spoke at the Peace Palace in The Hague after meeting with judges at the International Court of Justice, sometimes called the World Court, on Monday.

Peres said that economic sanctions against Iran may serve some purpose. But he noted that Syria in the past week agreed to give up its chemical weapons program only under the threat of use of force by the U.S. and pressure from Russia to comply.

Israeli Prime Minister Benjamin Netanyahu is due to meet with US President Barack Obama later Monday and discuss relations with Iran.
