UNITED NATIONS (AP) - Since the U.N. Security Council gave the go-ahead more than two months ago to add 3,000 more peacekeepers in eastern Congo, Secretary-General Ban Ki-moon has not gotten much help from 65 nations he approached.

In a letter made public Tuesday, Ban advised the council that only Bangladesh committed to offer more troops or police: an infantry battalion, a company of engineers and a police unit. Belgium said it would provide a C-130 military transport aircraft.

Five other nations said they would send intelligence experts, but not the equipment those people will need, Ban said.

Ban said that "troop-contributing countries have not been as receptive as we had hoped" despite the U.N.’s best efforts.

"The need for robust and highly mobile troops was particularly emphasized," he said. "I am especially concerned about the lack of formal offers of special forces companies."

Another big worry, he added, is that no nation has expressed interest or committed to providing another C-130 aircraft, 18 helicopters and 200 military trainers and advisers that are needed.

"These resources are essential for the mission’s mobility and rapid reaction capacity, which are vital if it is to fulfill the mandate set out by the Security Council," Ban said.

Japanese Ambassador Yukio Takasu, who took over the presidency of the Security Council this month, said its members have been discussing the shortfalls.

"I think the council needs to help with that to expedite the deployment," he said.

The council in November approved the temporary expansion to assist the 17,000 peacekeeping soldiers and police authorized in eastern Congo who now make up the U.N.’s largest such force. Since then, however, the conflict in the eastern Congo has taken a surprising turn.

Congo’s Tutsi-led rebellion had controlled a large swath of territory north of Goma, the regional capital. But then neighboring Rwanda turned on rebel chief Laurent Nkunda and detained him as part of a deal in which rebels from a splinter faction led by Bosco Ntaganda said they would operate under Congo’s army command and integrate into its ranks.

Rwanda gained approval to send thousands of troops into Congo and conduct a joint military offensive aimed at disarming Rwandan Hutu militias who fled to Congo in the wake of Rwanda’s 1994 genocide.

Eastern Congo has been wracked by violence since Rwanda’s 1994 genocide spilled war across the border. Rwandan Hutu militias who participated in the 1994 massacres of more than 500,000 people in Rwanda have sought refuge in Congo.

On the bright side, Ban said, four nations expressed interest in providing a second battalion and a fifth nation indicated it might be able to help with a second police unit.

The Economic Community of Central African States, whose members are laying the groundwork for a common market that can bring stability and raise standards of living, wrote Ban to say it could provide certain unspecified "capacities."

In December, Ban had cautioned that it could take up to a half-year to put the new peacekeepers on the ground. In the meantime, he had called on the European Union to send a temporary "bridging force." But the Congo said it expected only EU equipment.
