Recent estimates by the Office for the Coordination of Humanitarian Affairs (OCHA) put those who have been displaced at nearly one million, with more than half of them in the capital of Bangui alone, media quoted UN spokesperson Farhan Haq as saying at a news briefing.

"There has been a 40 percent increase in displaced people in Bangui since 24 December," he said.

Some 2.2 million people or about half the population of CAR needs humanitarian assistance, according to the OCHA's latest figures.

"But insecurity, as well as the lack of funding and access to people in need, continues to hamper aid efforts, including assessments and response," said Haq.

Insecurity hampered an emergency vaccination campaign against measles along with other aid services at the international airport in Bangui, he said.

The airport has given shelter to about 100,000 people.

CAR has been thrown into turmoil since Seleka rebels launched attacks an year ago and forced President Francois Bozize to flee in March 2013.

A transitional government has since been entrusted with restoring peace and paving the way for democratic elections but armed clashes have erupted again.

Last month, Christians and Muslims launched reprisal attacks against each other in and around Bangui, worsening humanitarian situations.
