WASHINGTON — American intelligence analysts have concluded that a recent Israeli airstrike on a warehouse in Syria did not succeed in destroying all of the Russian-made antiship cruise missiles that were its target, American officials said on Wednesday, and that further Israeli strikes are likely.

Israel carried out an attack on July 5 near Latakia to destroy the missiles, which Russia had sold to Syria. While the warehouse was destroyed, American intelligence analysts have now concluded that at least some of the Yakhont missiles had been removed from their launchers and moved from the warehouse before the attack.

The officials who described the new assessment declined to be identified because they were discussing classified information.

Israeli officials have said that they do not intend to enter the civil war in Syria, but that they are prepared to prevent sophisticated weapons from falling into the hands of Hezbollah, the Lebanese militia, which has joined the war to support President Bashar al-Assad of Syria and which controlled the warehouse where the missiles were stored.
