SKOPJE, Macedonia (AP) — Macedonia’s parliament approved the 2013 budget late Monday, amid clashes outside the building between rival groups of protesters that left 11 police officers and at least three opposition lawmakers injured, police and party officials said.

Lawmakers voted 65-4 in favor of the €2.7 billion ($3.6 billion) draft budget in the Christmas Eve vote, as riot police were need to separate pro- and anti-government protesters, who hurled rocks and eggs at each other. Three protesters were detained for questioning, police said.
