Family members — wearing black shirts bearing the picture of Clemence Felix Mtenga — broke down as they filed past his closed coffin at a ceremony in his home village of Kirwa in the Mount Kilimanjaro region.
Mtenga and another Tanzanian student, Joshua Mollel, 21, went to Israel in September for an agricultural internship program but both went missing after Hamas gunmen stormed across the border from Gaza into Israel on October 7, killing a reported 1,200 people and taking scores more hostage, according to Israeli officials.
Tanzania's foreign ministry confirmed his death in a statement last week, without elaborating on how he was killed. Authorities also said Mollel was still missing.
Friends who studied with Mtenga before he moved to Israel described him as being "lovely and friendly."
"It was sad and difficult to accept news of his death because we used to communicate with him almost every evening," said Anthony Kanyanza. "He was a leader of one of the class groups and we all enjoyed his company," Kanyaza added.
A member of the local choir, Mtenga had been due to graduate from his university in Tanzania last week.
"Clemence died innocent. Let's keep Israel and Palestine in our prayers every day to end this kind of innocent deaths," said priest Alfred Minja who led the burial service attended by government officials.
The head of Israel's international development agency Eynat Shlein had said on X, formerly Twitter, that Mtenga "was murdered by Hamas terrorists on October 7."
The two students were among about 260 Tanzanian youths who went to Israel for an internship in modern farming under a partnership program between the two countries.
Many of the places worst affected by the Hamas attacks were Israeli agricultural communes lining the region bordering the Gaza Strip.
Speaking to AFP by telephone, Mtenga's sister Christina Mtenga said the family had paid their "final respects."
