U.S. State Department spokesman Matthew Miller has voiced concern over Lebanese lawmakers who left on Wednesday a presidential election session to deny a quorum.

Miller said that Lebanese "urgently need a president who can enact reforms" to unlock International Monetary Fund support.

Syrian refugees languishing in camps in eastern Lebanon's Bekaa Valley for years say their hopes for the future are evaporating as their host country loses patience and international support dwindles.

Ibrahim al-Korbaw is only 48, but the hardships of war and poverty have aged the white-bearded man beyond his years.

Lebanese Forces leader Samir Geagea on Wednesday described the walkout of the pro-Suleiman Franjieh lawmakers from the 12 presidential election session as “a real and actual obstruction of the entire presidential election process.”

“Had the second round (of voting) been held today, we would have had a president now,” Geagea tweeted.

On Wednesday, supporters of former finance minister Jihad Azour accused Hezbollah and its allies of blocking the democratic process.

Hezbollah and Amal MPs had withdrawn following the first round of electoral voting on Wednesday, breaking the quorum, after Azour failed to reach the two-thirds majority needed to win in the first round.

MPs from the rival electoral camps on Wednesday claimed “victory” in a presidential election session that failed to produce a new president.

“The camp that is trying to impose its candidate garnered 51 votes, which means that there is a clear majority against the imposition process … Our rejection of imposition means that we have won,” MP Michel Mouawad of the pro-Jihad Azour camp said after the session.

Marada Movement chief Suleiman Franjieh on Wednesday thanked the 51 MPs who voted for him in the 12th presidential election session that was held earlier in the day without producing a winner.

“We also respect the opinion of the lawmakers who did not vote for me and this should push for constructive dialogue with everyone,” Franjieh added, in a tweet.

Parliament Speaker Nabih Berri urged Wednesday for dialogue after MPs failed for the 12th time to elect a president.

Berri called on parties to stop trading blame and to stop "spinning in a vicious circle."

Ex-minister and incumbent IMF official Jihad Azour on Wednesday thanked the Lebanese lawmakers who voted for him in the 12th presidential election session, which did not produce a new president.

"I hope that this development will be an incentive to converge on the need of getting Lebanon out of the crisis and move the process forward for the good of the Lebanese people," Azour said in an English-language statement.

Lawmakers in crisis-hit Lebanon on Wednesday failed for the 12th time to elect a new president, as bitter divisions between Hezbollah and its opponents marred the vote.

Candidates Jihad Azour and Suleiman Franjieh both failed to get across the line, with Azour garnering 59 votes and Frangieh 51 in the 128-seat parliament.

MPs Elias Jradeh, Halima Qaaqour and Cynthia Zarazir of the Change bloc and MPs Osama Saad, Abdul Rahman al-Bizri and Charbel Masaad of the Sidon-Jezzine bloc announced prior to Wednesday’s presidential election session that they would not vote for the candidates of the “sectarian parties.”

In a statement, the lawmakers said they would only vote for a candidate who supports the independence of the judiciary and backs holding corrupts accountable and resuming the probe into the Beirut port blast.
