International monitors investigating the Malaysia Airlines crash in eastern Ukraine said Friday the team was not given full access to the site and was greeted with hostility by armed men.

"There didn't seem to be anyone really in control," Michael Bociurkiw, spokesman for the Organization for Security and Co-operation in Europe team, told CNN's Christiane Amanpour.

Armed men, apparently pro-Russia militants, loosely guarded the area but couldn't answer the monitors' questions, he said. Bociurkiw said the group only stayed about 75 minutes and examined about 200 meters at the scene before being forced to leave.

Pieces of the airplane and bodies are spread over several kilometers. The OSCE team arrived at the crash site near Torez in a remote section of eastern Ukraine that's controlled by pro-Russian militants battling the Ukraine government.

The United States says a surface-to-air missile, possibly fired by the militants, took down Malaysia Airlines Flight 17 on Thursday as the plane traveled from Amsterdam to Kuala Lumpur in Malaysia. All 298 people on board died. U.N. Under Secretary General Feltman said 80 of the victims were children.
