Police have praised the "heroic" actions of a security guard killed in the deadly attack on an Islamic centre in the US city of San Diego, saying he prevented far worse bloodshed.
His actions had undoubtedly delayed, distracted and ultimately deterred the two suspects from reaching the area of the mosque where up to 140 children were located, San Diego Police Chief Scott Wahl told a press conference on Tuesday.
According to Wahl, the security guard exchanged fire with the 17- and 18-year-old attackers.
