During the meeting in here, the Secretary-General welcomed Ahmad al-Jarba's commitment to send a delegation to the conference, which is expected to take place in mid-November in Geneva and aims to resolve the conflict that is now in its third year.

Ban “urged the National Coalition to reach out to other opposition groups and agree on a representative and united delegation,” according to a readout of the meeting issued by his spokesperson.

He also stressed the paramount importance of embarking on serious dialogue as soon as possible, as well as the need to ensure accountability for war crimes, it added.

The conflict, which began in March 2011, has claimed over 100,000 lives, sent more than 2 million people fleeing for safety to neighbouring countries and displaced 4 million within Syria.

In the meeting, Ban underlined the suffering of the Syrian people on all sides, as a result of the conflict, and also the hardship of the neighbouring countries hosting Syrian refugees.
