Iraq fired another Scud missile at Israel Monday, and the army said it was trying to determine where it landed.

Reporters in Tel Aviv said they heard what sounded like U.S.-supplied Patriot interceptors being fired in an attempt to turn back the 12th rocket attack on the Jewish state by Iraq.The chief army spokesman, Brig. Gen. Nachman Shai, told Israel radio, "We have located one launching from western Iraq toward Israel."

He spoke shortly after air raid sirens sounded throughout Israel around 7 p.m. (10 a.m. MST), signaling a possible missile attack.

Ten minutes later, the all clear was sounded except for greater Tel Aviv and the area that includes the Israeli-occupied West Bank.

Iraq's last Scud attack came early Saturday morning. One missile struck the Tel Aviv area, injuring 26 people and damaging about 500 apartments.
