A new Israeli air defense system being developed in partnership with the United States met all its objectives in a series of recent live interception tests, U.S. and Israeli officials said Wednesday, putting it on course for deployment by next year.

The system, David's Sling, shot down targets simulating longer-range missiles like Scuds that could be fired at Israel from Syria and by Lebanon's Iranian-backed Hezbollah guerrillas.

Defense sources said the more recent tests took place last week and on Tuesday. The latter coincided with international negotiations on Iran's disputed nuclear program that have drawn censure from Israeli Prime Minister Benjamin Netanyahu and in turn soured his relations with U.S. President Barack Obama.
