Syrian opposition groups reject all negotiation with Assad's govt.

Syrian opposition groups meeting in Spain say they oppose all negotiation with President Bashar Assad's government unless it is aimed at his giving up of power.

Some 80 opposition representatives from inside and outside the country concluded a two-day meeting Tuesday, saying Assad would neither form part of any transition government nor have any role in Syria's future.

Mouaz al-Khatib, former chief of the Syrian National Coalition, said a decision on whether the opposition groups would take part in a new Russia-U.S proposed conference on Syria*s future in Geneva will be taken within two weeks.

The groups oppose Assad representatives taking part in the meeting.

At a news conference, the opposition members condemned increased intervention in the Syrian conflict by neighboring Lebanon's Hezbollah militant group, in support of Assad.
