Interior Cabinet Secretary Joseph Nkaissery has blamed non-governmental organisations (NGOs) and politics for the delay in repatriating refugees back to Somalia.
Mr Nkaissery asked the National Assembly's Security and Administration Committee to help the government in its efforts to send the refugees at Dadaab back home.
"We need to move. Many Somalis want to go back home, but they are held back by NGOs. If this committee can come up and demand timelines, then the government can move," he said at a meeting at County Hall.
Mr Nkaissery said that with the huge amounts of donor money they get, NGOs have been derailing the process and throwing roadblocks in its way.
He did not name the organisations.
He said that with elections in Somalia approaching, politicians from the country also fear that the returning refugees may tilt the political balance.
Kenyan politicians, on the other hand, would want the Kenyans who registered as refugees to get access to food and services or be resettled in developed countries, he said.
Wajir South MP Abdullahi Diriye said there are about 15,000 to 50,000 Kenyans hiding in the camps.
