Ousted Honduran President Manuel Zelaya began a new drive for support Tuesday in Mexico, where he backed a peace plan which would return him to power and accused his rivals of using delay tactics. Zelaya sought to increase the pressure on interim Honduras leader Roberto Micheletti to accept the peace deal put forth by Costa Rica President Oscar Arias, and said he would seek backing in Brazil later this week. 'We're ready to sign the Arias plan in Tegucigalpa to return me to the presidency... but we're not prepared to play a diplomatic game which only aims to delay the process of restoring democracy in the country,' he said. Zelaya also called for more pressure from the United States to help return him to power. The long-term backer of Honduras has so far refused to recognize Micheletti's government, has suspended military aid and revoked the diplomatic visas of some of the de facto leaders. 'The United States has taken action (but) it is still not sufficient and it has to toughen these actions, as do the rest of the countries in the Americas,' Zelaya said. Widespread international condemnation, aid freezes and crisis talks led by Costa Rica have so far failed to break the determination of the Honduran interim leaders, backed by the army and the courts, to maintain their stance. Interim leader Micheletti has rejected the Costa Rica crisis plan because it includes Zelaya's return to power. Mexican President Felipe Calderon received Zelaya with state honors more than one month after soldiers packed him onto a plane into exile over his disputed plans to change the country's constitution. Calderon also underlined Mexico's support for the stalled crisis plan, which he said was 'a base to reach a peaceful solution.' In a tense Honduras, police said a 45-year-old man was killed late Monday when a soldier fired on his vehicle for failing to stop at a military checkpoint. The death raised to five the number of people who have been killed in incidents related to the crisis that erupted on June 28 in the impoverished Central American nation. Micheletti's regime 'is a dictatorial government, a de facto government that is closed to democratic areas,' Frank la Rue, the UN Special Rapporteur on the right to free expression said Tuesday after talking with media organizations in Honduras. Radio Globo, one of the few Honduran media outlets to criticize Micheletti's government, said Tuesday it was threatened with closure. Zelaya traveled to Mexico after spending a week just meters (yards) away from Honduras in neighboring Nicaragua. The Honduran army, which has orders to arrest Zelaya, has twice blocked him from returning to Honduras. An increasingly frustrated Zelaya has threatened the interim government with 'generalized violence' if he is not restored to power. Zelaya took a sharp turn to the left after being elected to a non-renewable four-year term in 2005, influenced by regional firebrand leftist Venezuelan President Hugo Chavez. The Honduran Congress late Monday received a report by a seven-member panel recommending that lawmakers debate the Costa Rica-led peace deal, and particularly its call for an amnesty for those involved in the conflict.
