Chavez accuses Colombia of incursion

Venezuelan President Hugo Chavez has accused Colombia of carrying out a military incursion into Venezuela.



Mr Chavez says Colombian soldiers have recently been seen crossing the Orinoco river, which forms part of the border, and entering Venezuelan territory.



He claims that the incursion which Colombia denies happened was a provocation.



South American leaders are gathering in Ecuador for a summit which is set to discuss Colombia\'s planned accord to allow the US use of its military bases.



Chavez has been embroiled in a diplomatic row with his Colombian counterpart, Alvaro Uribe, since news of the plan emerged.
