International Flights Gradually Resume at Nairobi Airport Tony Karumba/Agence France-Presse - Getty Images Passengers waiting to board their flights at Nairobi's Jomo Kenyatta International airport on Thursday. NAIROBI, Kenya - International passenger flights were slowly resuming from Nairobi's main international airport on Thursday, one day after a devastating fire ripped through its main arrivals hall and disabled East Africa's busiest air transportation hub. Officials said they expected full operations to be restored by the end of the day. Several international departures and arrivals had been completed at the airport, Jomo Kenyatta International, by midday Thursday and dozens were scheduled for late evening. Kenya Airways, the country's flagship carrier, was operating at around 35 percent of capacity, but was expected to return to full service by late Thursday, said Michael Kamau, the government transportation secretary. "We expect that the normal flow of passengers will be restored from midnight," Mr. Kamau said. We are back on our feet. He said arriving passengers would be routed temporarily to the state pavilion at the airport, normally reserved for visiting presidents and heads of state. The Kenyan government wants to assure travelers of their safety, he added, "even though the level of comfort is not what they expect." Cargo flights, which resumed in part on Wednesday evening, will be allowed to operate only from 10 p.m. to 6 a.m. for the time being, Mr. Kamau added, giving priority to passenger aircraft until the backlog of flights has cleared. Confusion still reigned, however, among the makeshift check-in counters, as thousands of passengers who had been left stranded Wednesday sought to find their way aboard flights. Anet Ross, 45, visiting from Canada, said she and her husband were told at 6 a.m. to head to the airport for a flight home that was scheduled to leave at noon. "We were woken up very early," she said, "only to arrive and be told the flight has been canceled." A visibly frustrated Faith Imani, 25, said she rose at 3 a.m. and drove three hours from Eldoret, northwest of Nairobi, to catch her flight to Sydney, Australia, via Abu Dhabi, United Arab Emirates, on Etihad Airways. "I got here very early, but my agent just called me to tell me my flight has been canceled," she said. I am awaiting details from the airline, but we aren't getting information. No further details have emerged as to the likely cause of the fire, which began around 5 a.m. Wednesday and burned for several hours, eventually engulfing the international arrivals hall of the circular, 1960s-era terminal. There were no casualties. Mr. Kamau dismissed criticism that firefighters were slow to respond or insufficiently equipped to fight the blaze, which started in the immigration area in the central building. "The design of the airport made it extremely difficult even to hose water from any position," Mr. Kamau said. So there was a challenge. He said the initial fire was quelled using portable fire extinguishers before emergency services arrived. "I'd say that we are satisfied with the level of operations and services that we received from other government agencies and private firefighting companies," he said. Mr. Kamau said it was too early to estimate the cost of the damage to the terminal, which is in the midst of an expansion project, due to be completed in 2014. "The Kenya Airports Authority engineers haven't been allowed to access the area for security reasons," he said. The entire building requires renovation. Eunice Makambo, 41, traveling with her five children to Kigali, Rwanda, to visit her husband, said they had been stranded at the airport since Wednesday. "We have been told to wait," she said. Kenyan officials have been reluctant to suggest any link to terrorism, despite the fact that the fire coincided with the anniversary of the coordinated bombings of the American Embassies in Kenya and Tanzania on Aug. 7, 1998, which killed more than 200 people. Kenya is a crucial Western ally, abutting troubled areas of neighboring Somalia. Mr. Kamau stressed that the investigation into the fire's cause was still in its preliminary stages, adding that the Kenyan authorities were receiving technical assistance from international agencies and "friendly governments," though he did not elaborate. "We want to carry out a full investigation," he said. Reuben Kyama reported from Nairobi, and Nicola Clark from Paris. An earlier version of this article misstated the year that an expansion project at the Jomo Kenyatta International Airport is expected to be completed. It is 2014, not 2024.
