Djerba , Tunisia ( CNN ) -- Four more U.S. military flights were headed to Cairo from Tunisia on Sunday , evacuating Egyptians fleeing the Libyan conflict , a U.S. official said . One flight left early Sunday and three others will do so by Sunday afternoon , said Adam Lefringhouse , a defense attache at the U.S. Embassy in Tunis . On Saturday , U.S. military planes carried out similar evacuations , returning passengers to Egypt . There are a few thousand Egyptians left in Tunisia awaiting evacuation after more than 40,000 were taken home , said Firas Kayal , a spokesman for the United Nations refugee agency , on Saturday . Many countries , such as India and China , put in place well-organized evacuation operations for their citizens . But others , including Egyptians and Bangladeshis , have been left to fend for themselves . Kayal said Saturday more than 10,000 Bangladeshis are awaiting transport in Tunisia . Many of them have had to walk to the border because their money was stolen by soldiers and they could not pay for transportation costs . One man suffered a heart attack and died , aid officials confirmed . On Sunday , the British government said it will provide emergency evacuation flights to repatriate 500 stranded Bangladeshis . Three commercial charter planes will take the Bangladeshis home from Djerba airport later Sunday , the British government said . `` I have seen for myself the scale of the humanitarian situation on the Libyan border with Tunisia , '' said Andrew Mitchell , the International Development Secretary . `` I vowed that we would do everything possible to give those stranded shelter and get them back home as quickly as possible . '' Meanwhile , three people died and 14 were missing when they tried to get off a ship headed from Libya 's capital , Tripoli , to Crete , the Greek Ministry for the Protection of Civilians said Sunday . The ship was carrying about 1,280 passengers , mostly Bangladeshis . `` From the evidence gathered so far , it appears the passengers were trying to disembark the 'Ionian King ' ( Cypriot flag ) using a rope , '' the ministry said in a statement . The violence in Libya has generated an exodus out of the North African nation . Almost 200,000 people , a majority of them foreign workers , have fled Libya -- nearly 100,000 to Tunisia and a similar number to Egypt -- according to the office of the United Nations High Commissioner for Refugees . The numbers of people entering Tunisia daily from Libya dropped to 1,800 Thursday and Friday and stood at 3,000 Saturday . Previously , they averaged 10,000 to 15,000 people . Hovig Etyemezian , a field officer for the U.N. refugee agency , attributed the drop in part to fear and the manipulation of the flow of refugees by Libyan authorities . `` A lot of them were scared from leaving because of the fighting so they were staying in their houses , '' he said Saturday . `` We fear the regime might be blocking refugees from the border . '' The U.S. State Department said Saturday it would donate $ 3 million to the International Organization for Migration ( IOM ) as part of a joint U.S.-IOM partnership to help get home thousands of Egyptians and other nationals from Africa , South Asia and Southeast Asia . CNN 's Ivan Watson and Jomana Karadsheh contributed to this report .
