DUBLIN (AP) — Albert Reynolds, the risk-taking Irish prime minister who played a key role in delivering peace to Northern Ireland but struggled to keep his own governments intact, died Thursday after a long battle with Alzheimer’s disease. He was 81.

His eldest son, Philip, said he died around 3 a.m. at his Dublin home, where in recent years he required 24-hour care. The government ordered flags to fly at half-mast until Reynolds’ state funeral Monday.
