The discovery of suspicious letters on Thursday sent to three different locations across Connecticut has the FBI investigating whether the incidents are connected.
Keeney Street Elementary School in Manchester and Ruth Chaffee Elementary School in Newington are closed on Friday because of the letters.
The letter the Keeney School's main office received a letter contained white powder and a message about al-Qaida.
The school was placed in lockdown around 2 p.m, and remained on lockdown until students were dismissed at 3:25 p.m., their normal dismissal time.
It was the second school in Connecticut to receive a letter with white powder on Thursday.
The Ruth Chaffee Elementary School in Newington was evacuated after receiving a letter with white powder. It’s not clear if the school received a message about al-Qaida.
Students in kindergarten and first grade were moved to John Paterson, while students in grades 2, 3 and 4 were moved to John Wallace Middle School, according to the school district's Facebook page.
