Unclear as to the cause of the warning; we believe we were clear of the terrain according to the lights we could see. The event took place at Roanoke airport at night on a visual approach to 24. The Approach Controller turned us towards Roanoke airport at 4;000 feet. The runway was in sight [and] we were cleared for a visual approach into 24. Upon descending out of 4;000 feet we received a 'terrain pull up' aural warning. We executed the EGPWS procedure adding full power and pitching up. The controller levelled us off at 5;000 feet and vectored us around for another approach.  We were given a descent to 4;000 feet; once level we were given vectors back to the airport. When we approached the same mountain range as before the 'terrain' aural warning sounded again. This time without the 'pull up'. As we were climbing to 5;000 feet; another aircraft was descending to 5;000 feet and given vectors away from us. They were never close enough for an 'Resolution Advisory' or 'Traffic Advisory'.  We were then vectored for an ILS 34 and landed.
