Caracas, July 30 (EFE) Venezuelan President Hugo Chavez has frozen diplomatic and trade relations with Colombia in a spat over Colombian allegations that Swedish anti-tank weapons sold to Venezuela turned up in the hands of leftist guerrillas.

Citing Bogota's 'irresponsible' accusations, Chavez Tuesday Wednesday recalled the ambassador to Colombia, Gustavo Marquez, and froze bilateral 'diplomatic and trade relations'.

The leftist head of state said during a televised Cabinet meeting that any further 'aggression' against Venezuela by Colombian President Alvaro Uribe would lead to a definitive severing of bilateral ties.

'We would simply sever relations with the Colombian government, so let's prepare for that ... that's enough (in the way of) irresponsible (accusations) against our country,' Chavez said.

Chavez said a complete rupture would involve expropriating Colombian businesses operating in Venezuela, a threat he had made in the spring of 2008 when - amid an earlier diplomatic crisis sparked by a Colombian airstrike on a clandestine rebel camp in Ecuador, Venezuela's close ally - he ordered the closure of Venezuela's 2,219-km (1,380-mile) border with Colombia.
