(JTA) — A blizzard and avalanche in Nepal have killed more than a dozen trekkers, including at least two Israelis.

Extreme weather conditions spurred by the remains of Cyclone Hudhud struck the mountainous country on Tuesday, killing 17 hikers, including the Israelis, according to a report by the French news agency AFP. Other reports have varied, with the BBC placing the death toll at 21 trekkers in addition to three yak herders.

The death toll may rise as officials continue to hunt for some 100 missing trekkers.

Israeli media reported that the number of Israelis killed may be three or higher. The Israeli Foreign Ministry was waiting for reports to determine the official figures, according to Haaretz. Four Israelis have been rescued.

About a week ago, two Israeli tourists were killed in a rafting accident on the Apurimac River in Peru.
