Guatemala said Tuesday it will start training troops with neighboring Belize and improve cooperation to alleviate a blistering border dispute that saw a fatal shooting incident last month.

The accord was reached between the Central American countries' respective foreign ministers meeting on the sidelines of a humanitarian summit in Turkey, Guatemala's foreign ministry said in a statement.

Guatemala has deployed 3,000 troops to its disputed border with Belize following a shooting incident that killed a Guatemalan teen, Defense Minister Williams Mansilla said Friday.

"It is a preventive measure, it is not a declaration of war," Mansilla told AFP by telephone from northern Guatemala, where he was overseeing the deployment.

The government said Tuesday it is pursuing a "vigorous" investigation into a road-building company's near destruction of one of the largest Mayan pyramids in Belize.

The Ministry of Tourism and Culture expressed outrage at the demolition of the Nohmul complex in northern Belize to extract crushed rock for a road project. It said it is investigating to determine precisely how it happened.

John McAfee, founder of the eponymous anti-virus company, is on the run for killing another U.S. citizen in a resort town, Belizean police said Monday.

Police raided McAfee's mansion on Ambergris Caye, an island off the northeastern coast of Belize, late Sunday to question him about the murder of American Gregory Faull. But McAfee was nowhere to be found, said the head of the country's anti-organized crime brigade, Marco Vidal.
