Pakistan mourns as migrants ordered below deck in deadly Greek shipwreck tragedy.

Survivors of the shipwreck off the coast of Greece that killed at least 78 migrants, mostly Pakistanis, have reportedly said that they were forced below deck while passengers of other nationalities were allowed on the top deck. Pakistani police have arrested three traffickers in connection to the sinking, and the country is observing a day of mourning. Many Pakistanis pay up to $8,000 to traffickers to smuggle them to Europe through Iran, Libya and Turkey. The vessel was carrying as many as 750 people when it sank in international waters.
