PARIS — Protesters linked arms across an entrance at Paris' main airport on Friday to keep passengers off a Yemeni flight to Comoros — a route that saw a deadly crash this week, after years of complaints about dangerous conditions on the flight path to the Indian Ocean island nation.

The airline that operated the crashed jet, Yemenia, suspended its service to Comoros in response to the Paris protest and other demonstrations this week, accusing the protesters of "inadmissible violence."

Many in the Comoran community in France are angry that it took Tuesday's accident, which killed 152 people on Yemenia airlines' Paris-Moroni flight, to focus attention on the problems. They say that since 2004 they have been complaining about dangerous planes, unhelpful crews and stopovers in the Yemeni capital of San'a that last hours or days in stifling heat with little information and few basic services from the Yemeni airline.

Dozens of protesters gathered outside Charles de Gaulle's Terminal 3 and blocked passengers entering the terminal, shouting at passengers not to take the Yemenia flight.

Only 72 passengers ended up boarding the plane, which has a capacity of 180, and the flight didn't take off until noon, three hours after its scheduled departure, an airport official said on condition of anonymity because she was not authorized to speak to the media. She said, however, that the protest did not appear to have caused the delay.

Yemenia said in a statement later Friday that protesters have exposed airline personnel to "major risks" and as a consequence it suspended all flights to Comoros "until the situation calms." The airline defended its handling of the investigation and pledged to reimburse any unused tickets.

French Transport Minister Dominique Bussereau warned that Yemenia risked inclusion on a European Union list of banned airlines.

Khaled el-Wazeer, the Yemeni transportation minister, said that his government will provide documents within a week showing how the airline deals with technical problems on planes, a measure the EU has called necessary to keep it off the blacklist.

On Thursday, hundreds of shouting demonstrators at Marseille's airport tried to block passengers from boarding a Yemenia flight to the Comoran capital.

The airline said it was indefinitely suspending its flights from the Mediterranean port city to Moroni.

"SOS Trips to Comoros," a passenger group formed to push for better conditions, said that it had complained to airline officials as early as 2004 that planes on the route were unsafe.
