"Italy remained under steady migratory pressure as 23 000 migrants arrived there in August, close to the number from the same month of last year," the statement said, while the agency reported about 25,300 sea arrivals in July.
The statement added that the majority of migrants were from Nigeria, Eritrea and Bangladesh.
Europe has been beset by a massive refugee crisis, with hundreds of thousands of undocumented migrants fleeing their crisis-torn countries of origin in the Middle East and North Africa to escape violence and poverty. The majority of them cross the Mediterranean Sea and arrive in the European Union using southern EU nations as transit points.
According to the Frontex, about 118,000 people arrived in Europe via the Central Mediterranean route in the first eight months of 2016.
