Speaking at London School of Economics, Manna said the Syrian crisis would deteriorate if the status quo continues, adding that the world powers are responsible for the lack of a proper solution to the Syrian crisis.
Major powers have refused to take any measure for the settlement of the Syrian crisis so far and only resorted to theatrical conferences dubbed “Syrian friends”, he said, adding they have presented no democratic reform plan for the crisis-hit country.
The Syrian opposition figure supported the plan offered by the UN and Arab League envoy, Lakhdar Brahimi, for truce in Syria during the Eid Al-Adha holiday (starting on October 26), and expressed the hope that the measure could serve as a prelude to ceasefire in Syria.
Syria has been experiencing unrest since March 2011 with organized attacks by well-armed gangs against Syrian police forces and border guards being reported across the country.
Hundreds of people, including members of the security forces, have been killed, when some protest rallies turned into armed clashes.
The government blames outlaws, saboteurs, and armed terrorist groups for the deaths, stressing that the unrest is being orchestrated from abroad.
Brahimi had proposed in his recent visit to Tehran that a truce be put into effect between the Syrian government forces and the rebel groups fighting the Damascus government during the Eid al-Adha which has been announced a four-day holiday in Syria.
