BANGKOK, Thursday, Nov. 1 — A small group of Buddhist monks held a protest march in Myanmar on Wednesday in the first significant public show of defiance since troops crushed a pro-democracy uprising a month ago.

Reports from inside the country said 100 to 200 monks had defied a ban on assembly and marched through the streets of Pakokku, a medium-sized city in central Myanmar that was the site of a clash between monks and soldiers in September that set off the mass protests in larger cities.
