Israeli Prime Minister Ariel Sharon tells the army to enforce a no-go zone in Gaza to counter rocket attacks.
It is part of a series of new measures Israel says it will take to stop Palestinians firing missiles.
Palestinians have launched scores of rockets at Israel since Israel pulled out of the Gaza Strip this summer.
A Palestinian official rejected the plan, saying security forces in Gaza had been told not to leave their posts.
Interior ministry spokesman Tawfiq Abu-Khusah said the Palestinian Authority (PA) would "not yield to Israeli dictates and attempts to impose the zone by fire and bombardment", Palestinian radio reported.
Mr Sharon returned to work on Sunday after spending most of the week recovering from his stroke.
"We must make sure that [Palestinians] won't act against us, this is my policy and my instructions," Israeli media quoted him as saying.
The move followed talks on Thursday in which the prime minister told the army to do everything possible to stop rocket fire from the territory.
Palestinian militants have been able to fire missiles deeper into Israel since Israel withdrew from Gaza in September.
A rocket attack on Thursday wounded four Israeli soldiers.
A Palestinian man was killed when the army responded by firing artillery shells at the launch site in a field it said was empty.
Officials said on Thursday that the zone would be about 2.5km (1.5 miles) deep and run along the northern and eastern edge of the Gaza Strip.
