MANAMA, Bahrain (AP) — Bahrain’s top Shiite opposition parties said Saturday that they will boycott parliamentary and municipal elections slated for October.

The group of four, known as The National Democratic Opposition Parties in Bahrain, told a news conference that they are not taking part in elections until a political agreement that reflects the will of the people is reached. They said the agreement must “realize the principles of a democratic system of governance, where the people are the source of all authorities.”
