North Korea is denying suggestions it may be helping Syria develop a nuclear weapons facility.

The North Korean Foreign Ministry Tuesday dismissed U.S. media reports that Pyongyang has secretly offered nuclear cooperation to Syria.

The Washington Post newspaper reported last week that U.S. intelligence has acquired information, including satellite photos, indicating North Korea may be cooperating with Syria on some sort of nuclear facility. The information is said to have been provided mostly by Israel.

North Korea tested a nuclear weapon last year, but has since cooperated in six-nation talks aimed at ending its nuclear weapons program.

China announced this week that six-party talks scheduled for Wednesday have been postponed. It did not give a reason for the change.

A North Korean Foreign Ministry delegation arrived in Beijing Tuesday for talks with government officials. It is unclear whether the visit is aimed at sorting out a date for the nuclear negotiations.
