"The Israeli embassy in Cairo congratulates President Abdel-Fattah al-Sissi for winning a second presidential term," the embassy said on its official Facebook page in Arabic.
U.S. President Donald Trump expressed his “sincere congratulations” to Sissi on his reelection victory in a call on Monday, Egypt’s state news agency MENA reported.
Trump said in the call that the United States was keen on strengthening strategic relations and continuing to coordinate on key issues, MENA reported.
Egypt announced on Monday that Sisi had been reelected to a second four-year term with 97 percent of the votes - the same percentage he won when he first took office.
Turnout in last week's election was lower than it was in 2014, at 41 percent. Four years ago, he also won with 97 percent of the vote.

Sissi had long been virtually guaranteed victory after all serious opposition pulled out of the contest earlier this year.
Voters chose between Sissi, the general-turned-president who came to power after ousting in 2013 his elected but divisive Islamist predecessor, Mohammed Morsi, and an obscure politician who registered at the last minute and said he doesn’t oppose Sissi’s policies, Moussa Mustafa Moussa.
