Hezbollah leader Hassan Nasrallah says he regrets the kidnapping of two Israeli soldiers that sparked more than a month of warfare with Israel.
Nasrallah told Lebanese television Sunday if he had known the kidnapping would have led to such a war, he would not do it again.
He also said Italy and the United Nations have shown interest in taking part in possible talks on a prisoner exchange between Israel and Hezbollah.
Hezbollah seized the two Israeli soldiers during a cross-border raid July 12. The raid led to 34 days of fighting between Israel and Hezbollah fighters and widespread destruction in Lebanon.
U.N. Secretary-General Kofi Annan is to visit Beirut Monday. The United Nations plans to expand its 2,000-strong force in southern Lebanon to 15,000 soldiers.
Italy is to contribute up to 3,000 soldiers to the U.N. force.
Meanwhile, Israel says its forces have uncovered a Hezbollah bunker in southern Lebanon close to the Israeli border town of Rosh Hanikra. Israeli military officials say rocket launching materials were among the items found in the bunker.
