Venezuelan President Nicolas Maduro says officials have arrested three air force generals on charges of plotting a coup at a time of nationwide anti-government protests.

Maduro says the generals were brought before a military tribunal Monday night. He made the announcement during a meeting of South American foreign ministers aimed easing conflicts between the government and its increasingly strident opponents.

Maduro said Tuesday the attempt failed because younger officers became alarmed. He did not give any other details or provide names.

Maduro has routinely accused opponents of plotting a coup like the one that briefly ousted his predecessor Hugo Chavez in 2002. He has rarely given details and few arrests have been reported.
