UN Secretary General Ban Ki-moon arrived in Sri Lanka late on Friday night on a one day to assess the humanitarian needs of around 300,000 people displaced in the recent conflict with Tamil rebels in the north of the island, government officials said.
Ban arrived just after midnight local time and was due to spend Saturday visiting emergency camps for the displaced.
He will also meet Sri Lankan President Mahinda Rajapaksa, before leaving the country Saturday night.
President Rajapaksa Tuesday declared that the long-running civil war with Tamil rebels that lasted over 25 years has been brought to an end.
This was after the leadership of the rebels of the Liberation Tigers of Tamil Eelam including its leader Velupillai Prabhakaran was shot dead, according to the military.
