Israel has reportedly pulled its ambassador to Egypt from the country over security concerns.

Ambassador David Govrin, who took over the post last summer, was quietly pulled out of the country at the end of 2016 over concerns for his safety and has since been working from Jerusalem, with the hopes of returning to Egypt soon, Israeli officials told The Telegraph.

Israel officially reopened its embassy in Cairo last summer, four years after a mob had invaded the embassy there and forced staff to barricade themselves in a safe room, until Egyptian commandos rescued them after President Barack Obama intervened.

The report over Govrin’s withdrawal was first reported on Facebook by Amin el-Mahdy, an Egyptian political analyst. But el-Mahdy said the ambassador was pulled from Egypt due to Israeli-Egyptian political tensions over the Gaza Strip.

“Why is Netanyahu hiding from his people the details of his conflict with the Egyptian military junta, and with Sisi, his staunch ally?” el-Mahdy wrote on Facebook.

Israeli officials denied there was a political reason for the ambassador’s withdrawal, according to The Telegraph. Nevertheless, the officials did not identify a specific security threat, and the Israeli Foreign Ministry declined to comment on the report.
