Depeche Mode has been forced to cancel three more concerts as lead singer Dave Gahan's health has not sufficiently improved. He still needs more time to get over his bout with gastroenteritis.

The latest batch of cancelled shows are May 23 at Gwardia Stadium in Warsaw, POL; May 25 in Skonto Stadium in Riga, LAT; and May 27 at Zalgiris Stadium in Vilnius, LIT. Refunds are available at the point of purchase, or ticketholders can hold on to their ducats to see if any of the shows are rescheduled and use them then.

Previous cancellations were May 12 at Terra Vibe Park in Athens, GRE when Gahan was rushed to the hospital just before show time; May 14 at the Santralistanbul in Istantbul, TUR; May 16 at Izvor Park in Bucharest, ROM; May 18 at Vasil Levski Stadium in Sofia, BUL; May 20 at USCE Park in Belgrade, SER; and May 21 at Arena in Zagreb, CRO.

The band's next scheduled concert is on May 30 at the O2 in London, ENG. Depeche Mode's North American tour leg kicks off on July 24 in Toronto, ON, and winds down on September 5 in Fort Lauderdale, FL.
