The United States special envoy to Sudan Scott Gration on Wednesday expressed his country's keenness on improving the humanitarian situation in Sudan's Darfur region and delivering humanitarian assistance to the affected population.

"The main purpose of this trip was to learn about the situation in Darfur and the access that the humanitarian assistance was having," Gration told reporters after talks with Sudanese Minister of Foreign Affairs Ali Karti.

Gration said he had been given assurances from the Sudanese government that humanitarian assistance was flowing in and around the Kalma camp in the South Darfur State and that the situation there was on the mend.

The Kalma camp had witnessed armed clashes two weeks ago, which caused the Sudanese government to prevent United Nations agencies and international NGOs entering to the camp. However, the government reopened the access to the camp on Tuesday.

"I also received assurances that actions that would be taken by the government are actions that in accordance with international norms and that the human rights of the people would be respected in terms of the future of Kalma camp," Gration said.

The Sudanese government intends to move Kalma camp, which accommodates around 100,000 Internally Displaced Persons, from its current location, saying that the camp had become "a security threat" and "a shelter for criminals."

Gration on Wednesday started intensive talks with Sudanese government officials in Khartoum focusing on south Sudan referendum and the Darfur issue. "We have discussed what could be provided to help overcome the issues of difference. We have focused on some suggestions that could push the process forward and we have agreed to return to calm dialogue away from media battles," Karti said.

Gration is scheduled to leave on Thursday for Juba, south Sudan, to hold talks with local government officials on the referendum issues.
