Prosecutors say three men arrested in a raid on a Chicago apartment had planned to attack President Barack Obama's campaign headquarters, Mayor Rahm Emanuel's home and other targets, including police stations and police cars.

The trio was arrested Wednesday in a nighttime raid in the Bridgeport neighborhood on the South Side. They're accused of trying to make Molotov cocktails ahead of the two-day NATO summit that starts Sunday.

Defense attorneys told a judge on Saturday that undercover police are the ones who brought the Molotov cocktails, and that their clients were entrapped.

Bond of $1.5 million was set for each defendant. They have been charged with providing material support for terrorism, conspiracy to commit terrorism and possession of explosives.
