Progressive Socialist Party leader Walid Jumblat on Monday warned against ongoing internal divide.
"Regional and global changes push us to recognize the risks of ongoing internal divide," Jumblat wrote in his weekly al-Anbaa.
Jumblat hailed a weekend visit by a Hizbullah religious delegation to the Shouf Mountains.
"This step is a translation of what has been agreed upon during the meeting with Sayyed Hassan Nasrallah which will be followed by similar steps to strengthen the climate of calm and internal stability," he said.
Jumblat said the initiative has had a "positive impact on turning the painful page of May 7 (events) for good and open a new page through cooperation and restoring confidence."
He criticized a statement by U.S. Vice President Joseph Biden in which he gave Israel the right to attack Iran.
"What if Israel also decided to stage a pre-emptive attack on Lebanon and the Resistance?" he asked.
