Turkish President Recep Tayyip Erdogan's ruling party says it will seek a re-run of last week's mayoral election in Istanbul, citing alleged irregularities.

Ali Ihsan Yavuz, a ruling party deputy chairman, announced the decision on Tuesday after Turkey's top electoral authority rejected a request for a full recount of votes in the March 31 elections.

Yavuz maintained there were "significant events and situations" that affected the outcome of the vote and said the party would use a right for an "extraordinary appeal."

Erdogan's Justice and Development Party, or AKP, suffered a major setback in the elections. Opposition candidates won in Turkey's capital, Ankara, and squeezed out the ruling party in Istanbul.
