AlQa'dah 14, 1436, Aug 29, 2015, SPA -- Three Libyan nationals have been arrested in connection with a shipwreck this week believed to have led to the death of at least 250 migrants, dpa cited a report as indicating on Saturday. The three men, aged between 21 and 29, were arrested late on Thursday by Libyan authorities in the coastal town of Zuwara in a rare clampdown on people smugglers, according to the Malta-based Migrant Report. The arrests are linked to allegations that the men loaded a wooden boat with more than 430 migrants trying to reach Europe. It capsized around 5 to 10 miles off Zuwara. Police arrested the men following information relayed by survivors.
