SKOPJE, Macedonia (AP) — Chaos swept into Macedonia's parliament Thursday night when protesters stormed the building and attacked lawmakers to protest the election of a new speaker despite a months-old deadlock in efforts to form a new government. Dozens of protesters, some of them masked, initially broke through a police cordon after the opposition Social Democrats and parties representing Macedonia's ethnic Albanian minority voted to name a new parliament speaker. Shouting, hurling chairs and grabbing camera tripods abandoned by startled journalists, the protesters attacked lawmakers, including opposition leader Zoran Zaev, who was seen bleeding from the forehead. TV footage showed a bloodied Zaev and other Social Democrat lawmakers surrounded by protesters waving national flags, shouting "traitors" and refusing to allow them to leave. Police said lawmaker Ziadin Sela, who heads another ethnic Albanian party, was the most seriously injured and was taken to the emergency room of a Skopje clinic. Zaev, the opposition leader injured in the melee, suggested earlier in the day that a speaker could be elected outside normal procedures, an idea immediately rejected by the prime minister's party as an attempted coup.
