Kuala Lumpur, Shawwal 23, 1435, August 19, 2014, SPA -- A concrete section of elevated railway collapsed in Malaysia, killing three Bangladeshi workers, and prompting Prime Minister Najib Razak on Tuesday to order a probe, dpa reported. The 38-metre, 650-ton span broke free and fell to the ground late Monday, killing the victims immediately, police said. "Shocked and saddened to hear about the MRT (Mass Rapid Transit) site accident," Najib tweeted. "A full investigation must be carried out immediately to ensure this never happens again." One body has been recovered. The 51-kilometre MRT extension is one of several infrastructure projects to improve public transport in and around the capital, and is to be finished by 2017. --SPA 11:58 LOCAL TIME 08:58 GMT www.spa.gov.sa/w
