Sudan's official news agency says archeologists have reopened burial chambers in an ancient pyramid north of the capital, Khartoum.

SUNA says Tuesday the chambers are located at a depth of 10 meters (about 33 ) under a pyramid in the Meroe area. The UNESCO world heritage site is home to pyramids ranging from six meters (20 feet) to 30 meters (100 feet) tall.

It says from a Qatari mission discovered artifacts, including human and , inside the chambers.

The pyramids, with narrow bases and steep angles on the sides, were built by the ancient Nubian civilization between 720 and 300 B.C.

Qatar has pledged $135 million to renovate and support Sudan's antiquities.
