U.S. President Barack Obama on Monday expressed to President Michel Suleiman in a telephone call his concern about the role of Hizbullah in Syria, the White House said in a released statement.

"President Obama stressed his concern about Hizbullah's active and growing role in Syria, fighting on behalf of the (President Bashar) Assad regime, which is counter to the Lebanese government's policies," said the statement.

President Michel Suleiman denied on Monday receiving a warning from Israel that it would destroy Lebanon in case of a Hizbullah attack on the Jewish state.

Suleiman's press office said that the president hasn't received such a warning “although Israeli threats and violations of Lebanese airspace never stop.”

March 14 independent MP Butros Harb slammed on Monday attempts to paralyze constitutional institutions, urging parliamentary blocs to swiftly agree on a new electoral law.

“If circumstances obliged us to extend the tenure of the parliament then it must be for few months,” Harb said after talks with President Michel Suleiman at the Baabda Palace.

Caretaker Prime Minister Najib Miqati expressed regret on Monday on the sharp rift between Lebanese foes over the new electoral law, pointing out that there are only two options either political vacuum or extending the mandate of the parliament.

“Officials didn't act responsibly,” Miqati said in comments published in An Nahar newspaper.

President Michel Suleiman on Sunday condemned the rocket attack from Syrian territory on the Bekaa area of Hermel and denounced the Israeli mock raids over southern Lebanon.

In a press release, Suleiman stressed the need for “all warring parties in Syria to respect Lebanon's sovereignty and avoid military acts against Lebanese border areas that are targeting peaceful citizens.”

Caretaker Interior Minister Marwan Charbel reiterated on Sunday that he would ask the government to convene to approve the necessary funding to hold the elections and establish the committee that would supervise the polls.

In remarks to al-Mustaqbal newspaper, Charbel said: “I will hold the elections based on the valid law and let everyone assume his responsibility.”

MP Nicolas Fattoush has submitted a proposal on a two-year extension of parliament's mandate without coordinating with any side, the caretaker minister said Sunday, a day before an expected deal on running in the elections under the 1960 law.

“I made my proposal without coordinating with any party,” Fattoush told Voice of Lebanon radio (93.3) without confirming a report in An Nahar daily if his proposal was aimed at making a two-year extension.

President Michel Suleiman and Speaker Nabih Berri are likely to disagree on the extension of the current parliament's term given the political parties' failure to reach an agreement over a new electoral law, reported al-Akhbar newspaper Saturday.

Suleiman's circles said that the president reportedly opposes extending the term for more than four months.

President Michel Suleiman warned on Friday of extending the tenure of the parliament, calling on MPs to exert efforts to reach consensus over a new electoral law.

“Stepping over the people's will to select their representatives, which was stated in the law and based on democracy” is a red line, Suleiman told his visitors.

President Michel Suleiman is leaning towards advocating the formation of a 24-member government that distributes portfolios equally between the March 8, March 14, and centrist camps, reported the daily An Nahar on Friday.

His visitors quoted him as saying that he will endorse any cabinet line-up that enjoys the support of the majority of lawmakers.
