Twenty-three-year-old backpacker Omri Lahad was declared missing in South America on Thursday, after his family reported not having any contact with him for more than a month.

Israel has sent a search team to Colombia, where Lahad was last seen, but so far they have not found any signs of his whereabouts.

Lahad separated from his group of friends on October 26 in the town of Leticia on the border between Columbia and Peru. On October 28 he withdrew money from a local ATM before heading out on a cruise toward the Iquitos in the Peruvian rainforest.

Ever since then his family, from the northern town of Rosh Pina, has not had any contact with him.

The family have requested that anyone who has heard from or seen Lahad during the last month to contact them at the following e-mail address: findomrilahad@gmail.com
