A visit by Greece's foreign minister to Albania has been met with protests from the Cham community, which was expelled from northwestern Greece during World War II after Athens claimed they had collaborated with Greece's German occupiers.

A few hundred supporters of the Party for Justice, Integration and Unity skirmished with police Monday as they tried to block the entrance of the Foreign Ministry in the capital, Tirana, as Greek Foreign Minister Nikos Kotzias arrived.

Four issues have turned bilateral ties sour between the neighbors: the Chams' claims on their confiscated property, Greece declaring war on Albania in 1940, an unresolved maritime dispute and Greek claims of discrimination against the ethnic Greek minority in Albania.

Hundreds of thousands of Albanians poured to Greece after the communist regime fell in 1990.
