Two Queens men suspected of plotting to blow up Manhattan synagogues are due back in court today.

Ahmed Ferhani, 26, and Mohamed Mamdou, 20, could find out if a grand jury has indicted them.

Police say Ferhani was arrested after he tried to buy handguns, a grenade and hundreds of rounds of ammo from undercover officers.

Mamdou was picked up a few blocks away.

Prosecutors say an undercover detective secretly taped both men discussing a synagogue attack.

The men are charged with conspiracy as a crime of terrorism under a rarely used state law.

Both men deny the charges.
