— WSJ: Iran launched wave of attacks on US Navy ships days ago, unreported by US military
The attacks are part of a series, with Iran firing ballistic missiles at a US aircraft carrier and destroyer on Saturday.
No US ship was damaged in any of these attacks, but the attempts worry Washington, which believes Tehran seeks to escalate the conflict and use more advanced weapons, possibly with help from China or Russia.
Iranian officials claim they are using new missiles with advanced capabilities designed to target US warships, possibly equipped with electro-optical targeting systems.
US officials are concerned that China and Russia may be helping Iran track US ship locations.
