Martial law, special courts imposed on Guatemala

President Efrain Rios Montt imposed martial law on Guatemala Thursday, vowing that anyone caught with large amounts of weapons would be sentenced to death.

In a nationally televised address, General Rios Montt said special courts will be set up to try suspected rebels, ''and anyone convicted of subversive acts will be shot immediately'' by a firing squad. He said his June amnesty program for guerrillas would not be extended.
