The March 14 alliance called on Prime Minister Najib Miqati to immediately resign over Hizbullah's drone that penetrated Israeli airspace over the weekend, considering it a “defiance of the Lebanese people's will,” al-Joumhouria newspaper reported on Monday.

Leadership sources from the opposition held Miqati responsible for any new war between Lebanon and Israel, noting that Hizbullah insists on “usurping” the state's decision-making power and keeping Lebanon under the control of Iran.

Iranian President Mahmoud Ahmadinejad stressed on Sunday that Lebanon is a “center for resistance and perseverance against occupiers.”

He said: “Lebanon's resistance is a source of pride for the peoples of the region and all those seeking freedom and justice.”

Hizbullah's, Iranian-made, drone that penetrated Israel surveilled live images of “secret” Israeli military bases, according to Britain's Sunday Times newspaper.

The newspaper reported that the drone transmitted pictures of preparations for Israel's “biggest” joint military exercise with the U.S. army, which began last week.

A senior United Nations envoy on Sunday condemned a wave of attacks by Israeli settlers on Palestinian olive groves and called on Israel to punish the perpetrators.

"I am alarmed at recent reports that Israeli settlers in the West Bank have repeatedly attacked Palestinian farmers and destroyed hundreds of their olive trees at the height of the harvest season," said Robert Serry, U.N. special coordinator for the Middle East peace process.

Iran on Sunday scoffed at Israel's air defenses as it confirmed Tehran had provided Hizbullah with the sophisticated drone which overflew the Jewish state earlier this month.

Iran's "capabilities are very high and are at the disposal and service of Islamic nations," Defense Minister General Ahmad Vahidi said, quoted by state television when questioned on the origins of the unmanned aerial vehicle.

Israeli President Shimon Peres on Sunday told Brazil's foreign minister his country should boycott Iranian President Mahmoud Ahmadinejad in the future, Peres' office said.

"We expect Brazil to boycott future meetings with Ahmadinejad," Peres was quoted as saying to visiting Brazilian Foreign Minister Antonio Patriota in a statement.

Two men were killed and another two critically wounded on Sunday in an Israeli strike on central Gaza, Palestinian medics said in what was the third deadly raid in 24 hours.

The incident occurred just east of Deir al-Balah, with the Israeli military confirming it had targeted "a terrorist rocket squad."

Prime Minister Benjamin Netanyahu on Sunday said Israel was facing an increasing number of cyberattacks, just days after Washington issued a veiled warning to Iran over digital attacks on its interests.

"There have been increasing efforts to carry out cyberattacks on Israel's computer infrastructure," Netanyahu said at the weekly cabinet meeting, without giving details.

The head of the Mustaqbal parliamentary bloc MP Fouad Saniora accused on Sunday Hizbullah of following Iran's bidding through its recent sending of an unmanned drone to fly over Israel.

He said during a seminar in the southern city of Sidon: “Hizbullah is dragging Lebanon towards military operations and a possible Israeli retaliation that the country has not been consulted over.”

A leader of a hardline Islamist group that has claimed a spate of rocket attacks on Israel in recent days was among three Palestinians killed in Israeli air strikes on Gaza, sources on both sides said on Sunday.

Sheikh Hisham al-Saedini, 43, also known as Abu al-Waleed al-Maqdisi, one of the founding members of Salafist group the Mujahedeen Shura Council, was killed in a strike late on Saturday on the north Gaza town of Jabaliya, Palestinian security sources said.
