Kenya election: Last-minute court bid to block poll
Kenya's Supreme Court is to hold a last-minute hearing to decide whether the re-run of the presidential election can go ahead.
The court will hear an urgent petition by human rights activists arguing Kenya is not ready for the vote.
The election is due to take place on Thursday.
The Supreme Court in September took the unprecedented decision to annul the presidential election and demand a re-run.
Chief Justice David Maraga said the 8 August election had not been "conducted in accordance with the constitution" and declared it "invalid, null and void".

This was the first time in Africa that an opposition court challenge against a presidential election had succeeded.
President Uhuru Kenyatta, who is seeking a second term, has said the ballot must go ahead.
However, the main opposition candidate Raila Odinga is boycotting the vote.
He told the BBC's Newsday programme on Tuesday that it was a "sham" election "which will not represent the will of the people".
Mr Odinga says nothing has changed since the original poll and has called for "massive" demonstrations on election day.
On Monday, 20 Western diplomats said "growing insecurity", including inflammatory rhetoric and attacks on the election commission, made it more difficult to hold a legitimate poll.
Last week a senior official at the electoral commission fled to the US, telling the BBC she had received death threats.
Amid the growing tension, the bodyguard of Kenya's deputy chief justice was shot and wounded on Tuesday, police say.

The Supreme Court has agreed to hear the last-minute petition, which questions whether the electoral commission and its chairman will be able to conduct a free and fair election on Thursday.
It is asking for an entirely new election which could extend the process by months.
Difficult questions
Alastair Leithead, BBC News, Nairobi
There is ambiguity between electoral law, the constitution and how the courts have interpreted it.
The petitioners are asking the court to clarify its 2013 interpretation of the constitution – that if a candidate drops out, the whole months-long process should begin again, rather than simply holding a re-run.
That's the case Raila Odinga's lawyers cite in connection with his decision to boycott the poll.
According to the constitution the vote must be held before 1 November.
But last week electoral commission chairman Wafula Chebukati said "it's difficult to guarantee a free, fair and credible election". This leads to the question: Can the court allow the re-run to go ahead?
Another question is around how a potential constitutional crisis would be handled if the election is not held within the timeframe.
Wednesday has been unexpectedly declared a public holiday, but the Supreme Court says that will not affect its business.
