TEL AVIV, FEB. 3 (SUNDAY) -- Two Iraqi Scud missiles were launched against Israel last night and early this morning, apparently striking remote areas of the Israeli-occupied West Bank.

The Israeli military command said it had no reports of casualties although it said the second Scud attack caused slight damage. It provided no details. The points of impact have not been publicly identified.

These were the third and fourth Iraqi missiles fired at the Jewish state this past week, and both fell far short of Israel's civilian population centers on the Mediterranean coast and hit a predominantly Arab area.

None of the launchings came in the kind of barrages that punctuated Iraqi missile attacks on Israel the previous week, and Israeli military officials are cautiously suggesting that the Iraqi army's capacity and motivation for resuming multiple missile launchings against Israel may be diminishing.

Government spokesman Yossi Olmert said, "There is always the danger of more attacks, but we are not impressed with the aggression of {Iraqi President} Saddam Hussein. People are beginning to see light at the end of the tunnel."

However, civil defense authorities said an emergency alert will remain in effect indefinitely -- perhaps until the end of the Persian Gulf War -- because of the possibility of more incoming missiles and a danger that Iraq might launch chemical or biological warheads.

Last week, three major Scud barrages were launched against Tel Aviv and Haifa, heavily damaging a number of residential neighborhoods and causing four deaths and injuries to 190 people. Since Jan. 18, the day after U.S.-led air forces attacked Iraq and Kuwait, 29 missiles have been launched against Israel on nine days or nights.

Israeli military officials attributed the sharp drop in the number of missile attacks to constant observation of western Iraq by U.S. spy satellites and AWACS electronic surveillance aircraft, which has increased the ability of allied warplanes to bomb Scud launchers minutes after a firing is detected.

Pentagon officials said that on Thursday, immediately following a Scud launch that veered into the West Bank, the launcher and missile transport vehicles were destroyed by warplanes. Israeli military sources said such quick U.S. responses have significantly reduced Iraq's inventories of missiles in the western desert region, although they would not estimate how many Scuds Iraq has left.

Virtually all of the missiles launched against Israel so far originated from the same general area of western Iraq between two Iraqi air bases located along the Baghdad-Amman highway, about 350 miles northeast of here.

Col. Raanan Gissen, spokesman for the Israeli army command, said the two Scuds that fell in the West Bank Monday and Thursday could have been fired from launchers that had been moved east from the air bases in an attempt to avoid detection by the surveillance aircraft.

"As their capacity to effectively launch Scuds against us diminishes, their motivation may also be getting weaker. They've taken a lot of hits from the Americans in that area," Gissen said. He said that before Thursday's Scud attack, the Iraqis were believed to have had 10 mobile batteries left in the western desert, but that the total may be less now as a result of nightly attacks by U.S. warplanes.

However, Gissen said that until now, the Iraqis have been launching the Hussein version of the Scud, which has an effective range of approximately 360 miles, and that they still may be able to use the extended-range Abbas version, which can hit targets 540 miles away.

If that is the case, Gissen said, the Iraqis could launch the Abbas Scud from as far away as Baghdad and, temporarily at least, evade detection.

However, reserve Maj. Gen. Shlomo Gazit, former chief of army intelligence, said last night that doubts exist about the accuracy and dependability of the Abbas and that it could be ineffective against targets as distant as Tel Aviv.

"We don't know how many they have or what kind of accuracy they have. They have tested them, but we just don't know their capability," Gazit said.

Gissen said that even if all the al-Hussein mobile launchers in the vicinity of the two western desert air bases were destroyed in allied air strikes, Iraq has the capability of building new ones or even acquiring some.

"They {the launchers} are designed relatively simply. They're not that difficult to build. The Americans obviously are getting quite good at hitting these targets, but they {the Iraqis} can still surprise us. They can still put out one or two Scuds," Gissen said.
