Venezuela's Guaido says arrest of aide shows Maduro's weakness

CARACAS, March 21 (Reuters) - Venezuelan opposition leader Juan Guaido said arrest of his chief of staff by intelligence agents earlier on Thursday was a sign of weakness by President Nicolas Maduro's government.

"As they cannot arrest the interim president, they are looking to capture those closest to him," Guaido, who invoked the constitution to assume an interim presidency in January in a challenge to Maduro, said in a speech. (Reporting by Caracas newsroom)
