Earlier on Friday, a vote to elect a successor to Lahoud was postponed after the Hezbollah-led opposition threatened to boycott the poll.
The parliamentary vote set for Friday was put off for a week, the office of Nabih Berri, the parliament speaker, said just hours before lawmakers were scheduled to cast their ballots.
The vote had been the last chance to choose a president before Lahoud leaves office.
Many Lebanese fear the failure to elect a new president could throw the country deeper into political chaos and violence.
However, speaking to Al Jazeera, Nadim Shahada, a political analyst in Beirut, said: “In a way the Lebanese have shown they have a very healthy political system. In most countries this could be considered normal politics. There is no appetite for civil war.
In a statement read on his behalf, Berri said: “To allow for more consultations to arrive at the election of a president… the session is postponed to Friday, November 30.”
Politicians from the ruling coalition and the opposition have been unable to agree on a compromise presidential candidate, prompting fears of a power vacuum or the formation of two rival governments, as was the case at the end of the 1975-1990 civil war.
The army was deployed heavily in the capital on Friday, with tanks and troops at all major intersections, and the downtown area where the parliament building is located was declared off-limits.
Extra security measures were taken around a five-star hotel where dozens of anti-Syrian lawmakers have been staying for the past two months under guard for fear of assassination.

On Thursday, Michel Aoun, a Christian opposition leader, offered an 11th-hour solution to the political impasse, suggesting that his camp name an interim president and the ruling majority appoint a prime minister, but the offer was quickly rejected by the majority.
The ruling coalition, which has 68 deputies in the 127-member parliament, had repeatedly vowed to proceed with a simple majority vote if no agreement is reached.
But Hassan Nasrallah, the Hezbollah leader, warned that any attempt by the ruling coalition, which has a slim majority in parliament, would be tantamount to a coup.
With no agreement on a candidate to replace Lahoud, the president’s powers could pass to the government, in line with the Lebanese constitution.
But Lahoud has vowed not to hand executive power to the government of Siniora, which he does not recognise.
He has previously floated the idea of appointing an interim military government and he could also declare a state of emergency.
The US and its local allies blame Syria for the deadlock.
Hezbollah and its Christian allies, led by Aoun, say the US-backed majority wants to keep them from their rightful share in power and accuse Washington of trying to control Lebanon.
Bernard Kouchner, the French foreign minister, whose country has been leading efforts to resolve the crisis, left Beirut on Thursday after the latest in a series of failed mediation efforts.
The foreign ministers of Italy and Spain had earlier voiced pessimism after a last-ditch attempt to get the rival sides to agree failed.
The standoff between Siniora’s government and Hezbollah began after the Shia group, empowered by its 34-day war with Israel last year, pulled its five ministers from the cabinet in November 2006.
The army has warned against internal strife and both sides accuse the other of arming their supporters.
