London, April 11 - Rebellion is rife in Hungary, while Germany is in the throes of the war; witnesses in the empire since the outbreak of the war; troubles which are menacing the stability of the monarchy and threatening to repel her industrially as an active belligerent. News dispatches to this effect startled Europe today. The dispatches came from responsible well-trained correspondents, and in circles where the closest touch has been maintained with the conditions in the two Teutonic empires, not the slightest doubt is entertained that the news is accurate. Many believe that the situation is even worse than reported, notwithstanding the fact that Berlin this afternoon officially denied that there had been any riots or street fight in the region, asserting that the strike was "already settled." News of internal upheavals in Hungary came from "Vatican" advices, were quoted as saying that a revolution was imminent and as a result of disturbance at the capital. Cudapest and twenty live other cities and towns had been placed in a state of siege. Reports of the strike troubles in Hungary by the correspondents on the Hungarian frontier were sent by correspondents on the Hungarian frontier. They told of strikers, mostly munitions workers in Magdeburg, fortified capital of the Prussian Province of Saxony, attempting to burn the town hall.  Pitched battles were fought between the strikers and troops, many rioters being killed or wounded. The city has been declared in a state of siege, the dispatches say.
