Nearly 30,000 Afghans have arrived in Turkey in the last three months, the Turkish government said on Wednesday (April 25), after Amnesty International criticised the authorities "ruthless" decision to send more than 7,000 back to Afghanistan.
Interior Minister Suleyman Soylu said 29,899 Afghans had crossed into Turkey since January compared to 45,259 people in the whole of 2017, state news agency Anadolu reported.
"In recent months, we are facing a new refugee wave, especially from Afghanistan," Mr Soylu said, adding that 1,328 people smugglers had been caught by April.
Turkish authorities have sent back 7,100 migrants to Afghanistan since early April, rights group Amnesty said on Tuesday (April 24), as it denounced the "ruthless deportation drive".
"Thousands more are in detention, being treated more like criminals than people fleeing conflict and persecution," Ms Anna Shea, Amnesty researcher on refugee and migrants rights, said in a statement.
Migrants from Afghanistan and other countries affected by conflict and poverty often use Turkey as a transit country in the hope of reaching Europe.
According to Amnesty, there are 145,000 Afghans in Turkey.
The country is also home to more than 3.5 million Syrian refugees, as well as more than 300,000 Iraqi refugees, who have fled conflicts in their respective countries.
75,284 migrants have so far reached Turkey in 2018 compared with 172,745 last year, Mr Soylu said in a speech in the southern city of Adana.
