BERLIN: Two men have been convicted of attempted murder and sentenced to several years in prison for throwing a hand grenade onto the grounds of a home for asylum seekers in southwestern Germany.

The grenade was thrown over the fence of the facility in Villingen-Schwenningen in January and landed next to a container used by security staff. It didn't explode, and a bomb squad destroyed it.

Prosecutors suspect the attack was motivated by rivalry over contracts between security companies.

News agency dpa reported that the state court in Konstanz on Friday sentenced the two men alleged to have thrown the grenade to 3 and 3 ½ years in prison.

A third suspect was convicted of inciting the attack and sentenced to 3 ½ years.
