Hezbollah said all parties should expect "painful compromises" in order to reach a political solution to Syria's three-year-old conflict.

"The only viable solution to the Syrian crisis is a political one that avoids preconditions and sidelining influential parties," the group's deputy leader Sheikh Naim Qassem said at a meeting in Beirut with U.N. Special Envoy for Syria Staffan de Mistura, according to a statement by Hezbollah.

"Regional and international powers wasted three and a half years filled with killing and displacement as a result of the military option and exclusionary policies," he added.

Syria has been in the throes of conflict since 2011, when a peaceful uprising against the Damascus regime escalated following a violent government crackdown.

Hezbollah has been fighting alongside the Syrian regime since early last year.

Following a meeting with Lebanese Prime Minister Tammam Salam earlier Thursday, de Mistura said the international community was deeply concerned about Lebanon's stability given the ongoing conflict in neighboring Syria.

Hard hit by the conflict next door, Lebanon is currently hosting hundreds of thousands of Syrian refugees who have fled the violence back home.

The small coastal country has recently seen a surge in militant attacks in response to Hezbollah's role in the Syria conflict.
