SANAA (Reuters) May 14, 2011 - Plain-clothed gunmen opened fire on protesters in Yemen's southern city of Taiz on Saturday, wounding at least 15 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.
The plain-clothed men fired from rooftops in the restive city on protesters who demanded Saleh end more than three decades of rule in the Arab world's poorest country.
Three people were killed and 15 wounded on Friday when troops shot at protesters in Ibb, a city south of the capital Sanaa. The latest killings pushed the overall death toll since protests began to at least 170.
Security forces on Saturday arrested Ahmed al Musaibli, a leading broadcaster who had left state television to work for an opposition satellite channel, witnesses said.
Saleh, a wily political survivor, has clung to power despite defections from politicians, army officers and tribal leaders.
The Secretary-General of the Gulf Cooperation Council, Abdullatif al-Zayani, was due to arrive in Sanaa on Saturday for a three-day visit to try to resurrect the power-transfer deal, which the GCC brokered between Saleh and opposition leaders.
The GCC includes oil-rich neighbors on the Arabian Peninsula who share a stake in stability in Yemen, where the regional wing of al Qaeda is based.
In the central town of Rada, gunmen shot dead six soldiers and wounded seven in an attack on a checkpoint on Friday, a local official said, blaming al Qaeda.
Yemen also faces violence from separatists in its south, a tenuous peace with Shi'ite rebels in its north and insecurity resulting from tribalism and poverty.
In remarks published in the Saudi Okaz daily newspaper on Saturday, Saleh said that after any transfer of power he plans to go out on the streets as the opposition and "bring down the government again."
He said the deal which would see him leave office still needed further negotiation.
"There are some clauses in it that are obscure and ambiguous, requiring better clarification through direct talks with the Yemeni groups... in order to reach an agreement on the implementation timeframe that will follow," he was quoted as saying.
