Lebanon’s top Christian cleric said on Sunday the constitution had been violated in "cold blood" during a failed attempt to elect a new president last week, and warned that divisions in the nation had widened.

Patriarch Bechara Boutros al-Rai spoke in his first sermon since the Iran-backed Shi'ite group Hezbollah and its closest allies thwarted an attempt by factions including the main Christian parties to elect an IMF official as president.

Wednesday's events marked the 12th time parliament failed to elect someone to the post - reserved for a Maronite Christian in Lebanon's sectarian system and vacant since the term of the Hezbollah-allied Michel Aoun ended in October.

Rai, a critic of the heavily-armed Hezbollah, called Wednesday's session a "farce".

Rai has previously voiced criticism of Hezbollah, including in 2021 when it launched rockets at Israel.

The standoff has played out along sectarian lines with Christian parties supporting Jihad Azour, the IMF's Middle East director and an ex-finance minister, and Shi'ite factions Hezbollah and Amal against him.

Many Lebanese blame Iran for backing Hezbollah and interfering in the country's politics.

Azour won votes from 59 of 128 lawmakers, short of the 86 needed to win a first round vote. Suleiman Frangieh, a Hezbollah-backed Christian, got 51.

The Hezbollah-allied Parliament Speaker Nabih Berri ended the session when Hezbollah and its allies withdrew, denying a quorum for a second round when 65 votes are needed to win.

Greek Orthodox Archbishop Elias Audi, in his Sunday sermon, criticized Hezbollah and its allies without naming them, saying those who withdrew appeared "uninterested" in Lebanon.

Hezbollah and its allies attacked Azour, calling him a candidate of confrontation. Without naming him, Lebanon's Shi'ite mufti accused him of being backed by Israel.
