A Bangladesh Air Force F7 training aircraft crashed in Dhaka's Uttara this afternoon, according to Inter-Services Public Relations. 
The aircraft took off at 1:06pm, ISPR said in a text message. 
A senior official at Hazrat Shahjalal International Airport also confirmed the incident but did not provide immediate details regarding casualties or the cause of the crash.
On information, members of Bangladesh Army and eight engines of Fire Service and Civil Defence rushed to the spot and started rescue operations, according to a fire service notification.
The aircraft crashed inside the Milestone College compound in Uttara 17 around 1:30pm, a student said.
An eyewitness, Saadman Rhuhsin, who works at Friendship & Cooperation Recruitment — an office located near the school — said the jet crashed into the school building.
"Members of the army and fire service rushed to the spot and moved students and guardians to a safe place," he said.
People present there said the army personnel were seen rescuing the injured students in their arms to the rickshaw vans and other vehicles. 
A physics teacher of Milestone College told The Daily Star that he was standing near the 10-storey college building when the aircraft hit the campus. Shortly after 1:00pm, the plane crashed into the front side of the adjacent three-storey school building, trapping several students, he said.
The college teachers and staff rushed to rescue the students. Members of the army arrived shortly afterwards, followed by firefighters who joined the rescue operation.
