KAMPALA, Uganda (AP) — A fistfight broke out in Uganda's parliament Tuesday amid efforts to introduce legislation that could extend the president's decades-long hold on power. After opposition lawmakers accused a colleague on the government side of carrying a gun, a brawl broke out in which lawmakers pushed and punched each other before the speaker ordered body searches. A motion was due to be introduced Tuesday that seeks to remove a constitutional provision that prevents anyone over the age of 75 from running for president, but opposition lawmakers filibustered proceedings by repeatedly singing the national anthem.
