Illness forces Turkey's Erdogan to cancel election rallies and appearances.

Turkish President Erdogan has canceled upcoming election rallies after falling ill on live television due to a "stomach flu" while campaigning. Erdogan, seeking a third term as president, has been campaigning hard as he faces an especially strong challenge in the May 14 election. The latest opinion polls showed a slight lead for Erdogan's main challenger, center-left opposition leader Kemal Kilicdaroglu. Erdogan has been criticized for his increasingly authoritarian rule and handling of the economy and rampant inflation in recent years.
