CAIRO (AP) — The Latest on Egypt's presidential election (all times local):

9:35 a.m.

Egypt's Interior Ministry says it has killed six militants believed to be involved in a weekend bombing in the coastal city of Alexandria that killed two policemen.

The statement late on Sunday said the militants belonged to the Hasm movement and were killed in a raid on their hideout in Beheira province.

The Alexandria blast occurred when an explosive device that was placed under a car detonated as the city's security chief's convoy was driving by in Saturday. He was unharmed.

No group has claimed responsibility for the attack.

The bombing came just ahead of Egypt's presidential election tha got underway on Monday. President Abdel-Fattah el-Sissi faces no serious challenge in the vote.

Authorities consider Hasm, which routinely targets security personnel, to be a splinter group of the outlawed Muslim Brotherhood group. Militant attacks have surged in Egypt since the military's 2013 ouster of an elected Islamist president, Mohammed Morsi.

9:05 a.m.

Polls have opened in Egypt's presidential election with the outcome — a second term for President Abdel-Fattah el-Sissi — a foregone conclusion.

The election will last three days, starting on Monday.

A general-turned-president, el-Sissi is challenged by Moussa Mustafa Moussa, a little known politician who joined the race in the last minute to spare the government the embarrassment of a one-candidate election.

Moussa has made no effort to challenge el-Sissi, who never mentioned his challenger once in public.

Authorities hope enough people — there are nearly 60 million eligible voters — will vote in the balloting to give the election legitimacy.

A number of other presidential hopefuls stepped forward earlier this year, including some who might have attracted a sizable protest vote. But they were all either arrested or intimidated out of the race.

7:30 a.m.

Egyptians are heading to the polls but the presidential election this time is not about who wins — that was settled long ago — but about how many people bother to cast ballots.

Voting starts on Monday and is to last three days.

Authorities hope enough people will vote for President Abdel-Fattah el-Sissi to lend legitimacy to an election in which the only other candidate is an obscure politician who has made no effort to challenge him.

Cairo streets are lined with campaign banners and posters extolling el-Sissi, who has done little in the way of traditional campaigning, and has not publicly mentioned his ostensive challenger, Moussa Mustafa Moussa.

Several other presidential hopefuls who had stepped forward earlier this year have either been arrested or pressured to withdraw.
