7 wounded as plain-clothed men fire on Yemen protesters

SANAA - Plain-clothed gunmen opened fire on protesters in Yemen's southern city of Taiz on Saturday, wounding at least seven people, witnesses said, and a Gulf envoy was due to arrive to help revive a plan to end the crisis.
Protesters have been demonstrating across Yemen for months to try to oust President Ali Abdullah Saleh in an uprising inspired by movements that toppled the leaders of Egypt and Tunisia. A plan negotiated by neighboring Gulf states for Saleh to step down fell through last month when Saleh refused to sign.
