The leader of the Kyrgyz interim government said Friday that there will be no negotiations held with deposed President Kurmanbek Bakiyev.

There is no plan to have negotiations with Bakiyev, said Roza Otunbayeva, leader of the interim government.

"We will not let a civil war happen. We are doing everything possible to prevent it," she said.

Otunbayeva also blamed the Bakiyev administration for undermining the security situation in Bishkek.

"Three explosive devices were diffused today. These are subversive activities carried out by the Bakiyev administration, and this administration is not going to give up," said Otunbayeva as quoted by the Interfax news agency.

"We have the situation under control, but there are people who are trying to defend the old administration. I am meeting with people and they are saying they are ready to defend the new administration, the new government," she said.

Previous reports said two landmines were discovered by utility service workers at the crossroad of two central streets in Bishkek on Friday. Several apartment buildings, a theater and an educational institution were located in the area.

An earlier report said that Bakiyev has expressed his readiness to negotiate with the opposition.

"I will be glad to sit down with the opposition at the negotiating table," Bakiyev told the AFP in an interview in the southern Kyrgyz city of Jalalabad.

Kyrgyz opposition parties claimed to form an interim coalition government on Thursday, while Bakiyev refused to step down after clashes that left at least 76 people dead and 1,520 others injured.

All major departments of the Kyrgyz government on Friday lowered their flags in mourning for victims of the unrest across the Central Asian country over the past few days.

Officials from the interim government said law and order has been retained with no more looting.

"The situation in the capital city was under control by 01:00 a.m. on April 9 (0700 GMT) and streets were cleared of crowds of young rioters," according to the press service of the Kyrgyz Interior Ministry.

Public transportation resumed on Friday in Bishkek after Wednesday's unrest, Xinhua correspondents witnessed.

On Thursday, the Manas International Airport near Bishkek reopened and flights had been resumed.

The situation in the Central Asian country has raised global concerns, as several countries demanded a return to peace as soon as possible.
