Thousands of Malaysian demonstrators turned central Kuala Lumpur yellow for a second straight day Sunday with a rally demanding the prime minister's resignation over a corruption scandal, as the government threatened action against organizers.

The two-day rally, one of Malaysia's largest in years, has been mostly incident-free even though police declared it illegal, blocked the organizers' website and banned their official bright yellow T-shirt and logo.

Malaysia's capital braced for possible confrontations Saturday between demonstrators seeking the premier's ouster over corruption allegations and police who have declared their planned two-day street rally illegal.

The country's leading civil society alliance vows to turn out tens of thousands of people in Kuala Lumpur and two other cities for the weekend demonstration, which is due to kick off at 0600 GMT on Saturday.

The final report into the downing of Malaysia Airlines flight MH17 over war-torn eastern Ukraine last year will be released in October 13, Dutch investigators said on Thursday.

"The Dutch Safety Board (OVV) informed relatives and the accredited representatives to the investigation that the board will publish the final report on the investigation into flight MH17 on 13 October 2015," the board said in a statement.

Ten Malaysians have been arrested for fostering suspected links with the Islamic State group and planning attacks in the country, police said.

Malaysia's national police chief Khalid Abu Bakar said late Thursday that the 10 individuals were allegedly "planning to obtain weapons to launch attacks in the country and arrange logistics for Malaysians to join the IS in Syria".

A Malaysian team inspecting debris that washed up in the Maldives has so far found nothing that came from missing flight MH370, Malaysia's transport minister was quoted as saying on Friday.

Malaysia sent experts to the Maldives this week to check on reported debris found on the coral atoll nation after a wing part from the ill-fated plane was found on Reunion island in the Indian Ocean to the south.

An MH370 families organization said Wednesday it would not accept the Malaysian government's declaration that wreckage found on an Indian Ocean island came from the ill-fated flight until more analysis is completed, and called for an impartial investigation.

The statement by Voice 370, an international next-of-kin group, adds to doubts over the debris that have been expressed already by a number of individual family members.

Investigators probing the shooting down of Malaysia Airlines flight MH17 said Tuesday they had identified possible Russian-made BUK missile fragments from eastern Ukraine, where the plane crashed.

International and Dutch investigators are probing "several parts, possibly originating from a BUK surface-air-missile system," said a joint statement from prosecutors and the Dutch Safety Board (OVV).

Malaysia will send a team to the Maldives to determine whether debris reportedly found there is further wreckage from flight MH370, the transport minister said Monday.

Transport Minister Liow Tiong Lai said Malaysia had been "officially notified" by authorities in the Maldives of objects found there, whose origin remains unverified.

France launched a hunt for more wreckage from the ill-fated MH370 plane off Reunion island on Friday in a fresh effort to shed light on one of aviation's biggest mysteries.

The tiny French Indian Ocean territory has been under intense scrutiny since a beach cleaner found a washed-up wing part last week, which Malaysian Prime Minister Najib Razak later declared was part of the Boeing 777 that mysteriously vanished 17 months ago.

Chinese relatives of passengers aboard missing flight MH370 on Friday marched to Malaysia's embassy in Beijing, some demanding to be taken to Reunion island where suspected wreckage from the plane was found.

Most of the aircraft's passengers were Chinese, and around 30 of their relatives protested near the embassy, as dozens of police blocked off roads near the building.
