WARSAW, Oct 12 Reuters Poland and the Czech Republic will extend temporary controls on their borders with Slovakia into November as countries seek to restrict the flow of illegal migrants.

The Polish government has decided to extend the controls by 20 days to Nov. 2, the interior ministry said in a statement. Interior Minister Mariusz Kaminski had said earlier that it would do so following a similar order announced by the Czech government on Wednesday evening.

The two countries, along with Austria, tightened their borders with Slovakia on Oct. 4 to guard against smugglers and a rise of illegal migrants.

There are good results, there are clear effects, Kaminski said.

Slovakia is a transit country for migrants mostly from the Middle East and Afghanistan who are seeking to reach Germany after crossing into the European Union through Hungary from Serbia, which is not in the EU.

On Wednesday, Slovakia extended its own border controls with Hungary until Nov. 3. The number of migrants entering Slovakia has risen elevenfold to nearly 40,000 this year, government data shows.

Last month Germany also introduced checks on its borders.

Poland, Slovakia, the Czech Republic, Hungary, Austria and Germany are all part of the EU39;s Schengen openborder zone.
