Polish military plane crash kills at least 7

(CNN) - At least seven people were killed Wednesday when a Polish military transport aircraft carrying passengers who had attended a flight-safety conference crashed in northwest Poland, military officials said.

Defense Ministry Col. Cezary Siemion confirmed seven deaths, but said that number was likely to climb. He said there were 18 people on board - 14 passengers and four crew members.

The Spanish-built CASA transporter crashed near the town of Miroslawiec, a few hundred kilometers northwest of Warsaw, around 7 p.m. (noon ET).
