"There are some border places where the Israelis are used to crossing. I say it in public: It is our right to plant explosives there and prepare ambushes there," Hasan Nasr Allah, Hizb Allah secretary general, told thousands of supporters on Sunday.
"The Israeli enemy has no right to ask the United Nations Interim Force in Lebanon to come and remove them."
UN Secretary-General Kofi Annan expressed concern two weeks ago about Hizb Allah planting mines along the border, as well as Israeli flights over southern Lebanon, describing border
tensions as "frequently high and the situation fragile".
The UN Security Council at the same time urged Lebanon to assert its authority across the south rather than leave it in the hands of Hizb Allah, which fought the 22-year Israeli occupation of the region until Israel withdrew in May 2000.
Nasr Allah said while Israeli forces were able to cross into
Lebanon, Hizb Allah had the right to defend the area.
"Is it required that this area be left abandoned so that the Israelis enter to plant explosives here and there, to kill someone or kidnap someone?" he asked.
Nasr Allah was speaking to Hizb Allah supporters gathered in
Jibsheet in southern Lebanon to celebrate the release of
hundreds of Arab prisoners from Israel under a swap agreement.
Nasr Allah said he would stipulate to German mediators that secrecy surround the next swap, expected within three months.
"I have agreed with my brethren that we have to enter this stage with secrecy, because media statements and speeches could harm or block it," said Nasr Allah. He blamed Israeli news coverage of the last swap for repeated delays.
The next stage of the talks is expected to focus on the fate of missing Israeli airman Ron Arad, who bailed out over Lebanon in 1986, and include the release of Samir al-Qantar, the last Lebanese prisoner in Israel.
"There are some border places where the Israelis are used to crossing. I say it in public: It is our right to plant explosives there and prepare ambushes there."

Hizb Allah destroyed an Israeli bulldozer in the border region by missile last month, killing the soldier driving it.
"The fate of the Israeli bulldozer is what any Israeli will meet if they put a foot inside Lebanese land or water," Nasr Allah told the crowd on Sunday.
