The Israel Defense Forces (IDF) vowed on Wednesday to face any development following its withdrawal from the Gaza Strip after 22-day intensive offensive against rocket attacks launched by Hamas-led militants.

The IDF is prepared for any development after Gaza pullout, said an IDF statement sent to Xinhua.

However, the statement did not elaborate the preparation.

The statement came just after an IDF spokesman told Xinhua on Wednesday that the Israeli army has completed troops pullout from the Hamas-ruled Gaza Strip.

The last Israeli soldier left the Palestinian coastal enclave this morning and Israeli army is redeploying alongside the Israel-Gaza border of the Israeli side, said the spokesman.

Recent local media reports indicated that thousands of regular troops and an additional several thousand reservists had entered Gaza since Israel launched the ground incursion on January 3.

Local news service Ynet reported on Wednesday that the Israeli army continues to maintain a high state of alert on the strip's border in case the ceasefire with Hamas might be violated.

The IDF was originally planned to leave Gaza before the inauguration of new U.S. President Barack Obama on Tuesday, but several shooting incidents in the area forced the soldiers to delay their pullout, according to Ynet.

Palestinian gunmen opened fire on Israeli troops in two separate incidents in Gaza Tuesday, and several mortar shells were fired at Israel. No injuries or damage were reported in any of the attacks.

IDF sources estimated that calm would prevail in Gaza in the near future, while Hamas is busy reconstructing the strip's infrastructure and rebuilding its organization, said Ynet.

Earlier on Tuesday before Obama was inaugurated, Israel had withdrawn most of its forces, which was considered by analysts as an attempt not to cloud the start of a new era in a key alliance.

On Sunday evening, the Jewish state actually began pulling out its forces in what it called an overall redeployment, hours after Hamas and other Gazan militant groups announced that they decided to stage a one-week ceasefire with Israel, during which they demand Israel withdraw its troops.

Israeli Prime Minister Ehud Olmert Saturday evening announced a unilateral ceasefire in Gaza, beginning from 2:00 AM (0000 GMT) on Sunday.

At a press conference in Tel Aviv, Olmert said that the goals of the operation in Gaza had been "met in full."

The Jewish state has repeatedly said that the goals of the operation are to deal Hamas a harsh blow, force the militant group to put an end to anti-Israel activity and stop weapon smuggling from Egypt to Gaza through tunnels.

The 22-day-long IDF operation, dubbed Cast Lead, began on December 27, killing more than 1,400 Palestinians and wounding some 5,500 others.

On the Israeli side, 13 people were killed since the operation, including four killed by rockets from Gaza. The other nine were soldiers killed in Gaza ground battle.
