( CNN ) As Nepal grapples with an earthquake that has killed more than 3,400 people , Ronen Ziv worries about someone he has never met . His unborn baby is due this week in Kathmandu . He had tickets to travel to Nepal for his child 's birth from a surrogate mother , but now he has no choice but to wait in his native Israel for news . `` It 's terrifying , '' Ziv said . `` I can tell you I did n't get much sleep ... all my thoughts and all my prayers are for the surrogate mother and the unborn child . '' Nepal is a popular place for Israeli couples to have surrogate children . Ziv 's first child , a 15-month-old daughter , was born to a surrogate mother in Nepal . Ziv and his partner , Tom , traveled to Nepal for the birth . They were planning on making the trip once again , but the earthquake forced them to change their plans . Companies that help arrange surrogate pregnancies estimate 25 couples are now in Kathmandu with newborn surrogate children , while 10 to 15 surrogate mothers are due to give birth in the coming weeks . The country is also a popular spot for Israeli travelers . The Israeli Ministry of Foreign Affairs estimates there are about 600 to 700 Israelis in Nepal . Israel Defense Forces is sending 260 emergency responders to Nepal , including search-and-rescue teams . The group is also bringing almost 100 tons of medical aid supplies . Ziv says his baby is in a breech position , requiring a cesarean section . In the current chaos of Kathmandu , he worries his surrogate mother , Nafisa Shaje , will not get the proper medical attention required for a safe and healthy birth . Ziv would prefer Shaje fly to Israel , where hospitals can provide the needed medical help . But with only days left until the baby is due , Ziv said putting Shaje on a plane might not be possible . `` If anything else happens , it could very quickly go to absolute catastrophe , '' Ziv says . Hospitals in Nepal have been flooded with injured quake victims . Some have been turned away so doctors can tend to the most severely injured . Cila Tamir , Ziv 's attorney , has been working with the Ministry of the Interior to try to bring Shaje to Israel . `` She has no place to deliver . No conditions , '' Tamir said . `` Everything is ruined there , and I 'm sure that the hospital does n't function normally because of the casualties and the injuries . ''
