Supporters of Turkish president Recep Tayyip Erdogan have taken to the streets to celebrate a 'vicotry' in the referendum, despite votes still being counted.
About 51.2% of the votes are 'Yes' with more than 98% of the ballot boxes opened.
Meanwhile, opposition parties of the Republican People's Party (CHP) and the pro-Kurdish Preople's Democratic Party (HDP) have demanded a recount of the votes.
Opposition leaders challenged claimed that 1.5 million votes are invalid.
