The breakaway Georgian republic of Abkhazia has rejected a U.S. proposal to deploy an international police force there, its leader said Tuesday.

The regional government, which is not internationally recognized, instead pledged to keep Russian peacekeepers on the ground, despite Georgia’s accusations that they are fomenting tensions.

The U.S. State Department said Monday that Abkhazia “urgently” needs an international police presence in areas where recent bombings killed four people and wounded five. It also called on Abkhazia to resume peace talks with Georgia.

“We are not going to listen to any recommendations from the State Department, which always has a unilaterally pro-Georgian position,” Abkhazia’s leader Sergei Bagapsh told journalists.

He also refused to resume talks unless Georgia stops what he called “terrorist attacks.”

Russia, meanwhile, proposed a resolution at the U.N. Security Council in New York that urges the council to express concern over the bombing.

Russia’s U.N. Ambassador Vitaly Churkin told reporters he had reason to believe the blasts were “of Georgian origin” to whip up tensions in the area and derail peacemaking.

The proposed resolution would also require Georgia to take “urgent steps” to prevent unauthorized troops from entering Kodori Valley on the border between Georgia and Abkhazia.

Russia recently increased its peacekeeper contingent in Abkhazia _ a move Georgia claimed was part of a Moscow plan to annex the region. Russia also supports separatists in another breakaway Georgian region, South Ossetia, and most people in both regions carry Russian passports.

Abkhazia claims the explosions are part of a Georgian government effort to retake control of the regions by force. Georgian officials deny responsibility for the bombings and call them provocations.

South Ossetia authorities said they detained four Georgian officers in the border area. The officers were released Tuesday evening, Georgian Defense Ministry spokeswoman Nana Intskirveli said.

Separatist government spokeswoman Irina Gagloyeva said the soldiers were collecting reconnaissance data for Georgian artillery. But Georgian Gen. Mamuka Kurashvili said the detained officers were visiting friends and were illegally captured by a militant group.

Last week, Georgian forces shelled several South Ossetian towns, killing two people and wounding 11 others. The Georgians said their troops had to fire back because the separatists attacked them.

Abkhazia and South Ossetia _ which split off in a separatist war in the 1990s _ have become a focus of Russia’s efforts to thwart pro-Western Georgian President Mikhail Saakashvili’s drive to take his country into NATO.

Russia, meanwhile, proposed that the U.N. Security Council require Georgia to take “urgent steps” to prevent unauthorized troops from entering Kodori Valley on the border between Georgia and Abkhazia.

A draft resolution Russia put before the 15-nation council in New York also would have its members express concern over Sunday’s bombing in the breakaway republic that killed a U.N. translator and three others and wounded five. The council renewed the mandate of the U.N. mission there in April to try to resolve the Georgian-Abkhazian dispute.

Russia’s U.N. Ambassador Vitaly Churkin told reporters he had reason to believe the blasts were “of Georgian origin” to whip up tensions in the area and derail peacemaking.
