Athens: The Greek island of Lesbos is "on the verge of explosion" with the arrival of more than 15,000 mainly Syrian refugees pushing local resources to the limit, the immigration minister said on Monday.
Yiannis Mouzalas told To Vima radio that boats taking refugees to the Greek mainland would soon be using a second port to ease pressure on the island of 85,000 inhabitants.
"Mytilene currently has 15,000-17,000 refugees and this is the official figure from all services," Mouzalas, a junior interior minister, told the station.
"We are placing emphasis here because the situation is on the verge of explosion," he said.
The minister said the second departure point would open at the fishing village of Sygri in coming days.
Lesbos is one of several Greek islands struggling with an influx of thousands of migrants, many of them Syrian refugees, setting sail from the nearby Turkish coast.
"We hope that in the next five days the (islanders) and the refugees will see clear signs of improvement," Mouzalas said.
Lesbos mayor Spyros Galinos on Saturday had called on the island residents to boycott national elections on September 20 in protest at the refugee buildup.
"We call on the people of Lesbos not to take part in the upcoming elections and we state our intention not to place ballots unless immediate measures are taken to deescalate the situation," Galinos said in a statement.
There have been clashes on Lesbos in recent days between police and migrants, and between migrants of different nationalities, over delays in the registration process that have held up their journeys on to other countries in Europe.
Police reinforcements were sent today to the island after Syrian refugees were targeted with Molotov cocktails.
Two 17-year-old boys were arrested after throwing two Molotov cocktails at refugees sleeping in a park, injuring a Syrian man in the process.
Syrians have been granted priority in the registration process, sparking tensions with other migrants forced into long waits on the island.
More than 230,000 people have landed on Greek shores this year, with the numbers soaring in recent weeks as people seek to take advantage of the calm summer weather.
The Greek state has chartered a ferry, the Eleftherios Venizelos, to transport refugees from the islands to the mainland.
