Western officials and outside analysts believe that the European dictatorship is aiding Bashar al-Assad's crackdown.
U.S. officials are increasingly concerned that Syrian strongman Bashar al-Assad is receiving new military assistance from Belarus, a tiny nation which appears willing to flout the international effort to isolate the dictator and force him from power.
Western officials and outside analysts say that Belarus is providing Damascus with technology that would improve the capabilities of Assad's surface-to-surface missiles, one of the Syrian military's primary weapons during its brutal ongoing crackdown on rebels throughout the country.
The technology would increase the accuracy of the missiles, making it easier for Assad's forces to target and destroy even well-entrenched and well-hidden rebel positions.
Scott Johnson, an analyst for IHS Jane's, which researches militaries around the world, said that Belarus's state-owned weapons-development company is suspected of working with its Syrian counterpart to build new "fiber-optic gyroscopes," small pieces of equipment that can make surface-to-surface missiles significantly more accurate.
