BELGRADE, February 28 (RIA Novosti) - Serbia is continuing to recall its ambassadors from those countries, which have officially recognized Kosovo's independence, as it summoned diplomatic heads in Austria and Switzerland home Thursday.

Serbia has already recalled its ambassadors from the United States, Italy, Germany, Belgium, Australia and Peru, which have all recognized Kosovo's independence announced on February 17.

The Serbian Foreign Ministry said in a statement that other ambassadors should leave those countries supporting Kosovo's new status as soon as possible and has also issued a note of protest to the Polish government, which announced it would recognize the former Serbian province.

Kosovo's independence is opposed by Serbia and Russia. Moscow said it will block any move by Kosovo to join the United Nations.

Protests against Kosovo's independence turned into street riots in Belgrade last week, leaving at least 130 people injured.
