Honduras' post-coup leader Roberto Micheletti on Tuesday dismissed the country's ambassadors to the United Nations (UN) and the Organization of American States (OAS).

The interim government decided to sack Jorge Artugo Reina, the ambassador to UN, and Carlos Sosa Coello to OAS, and they will be no longer entitled to make any statement on behalf of the new government, Micheletti told a press conference held in Tegucigalpa.

Micheletti said he was considering two new nominations, who will "respect the true facts" and "will comply with the decision of the government."

Reina and Coello, both appointed by the ousted president Manuel Zelaya, have strongly denounced the military coup that drove Zelaya from power Sunday.

At a UN General Assembly meeting on Monday, Reina urged the world not to accept any "illegitimate government" that took Zelaya's place.

Also on Tuesday, Honduran military spokesman Ramiro Archaga told Xinhua late Tuesday that the country's Supreme Court was attacked by unidentified attackers with a grenade.

"Fortunately, the grenade did not explode," he said, adding that bomb disposal experts were on their way to defuse the grenade.

According to the spokesman, the attackers hurled the grenade at the court's entrance in the evening while driving a light-colored vehicle.

Currently, the situation in the Central American country remains unstable due to large demonstrations against the Sunday coup that ousted President Zelaya.

Honduras' Congress quickly installed congress speaker Roberto Micheletti as the interim president and a new government, arousing demonstrations of pro-Zelaya supporters.

The demonstrations went violent and have already killed two people and injured dozens.
