ISTANBUL, Sept 8 (Reuters) - Netblocks, a global

internet monitor, said on Monday that access to online platforms

including X, YouTube, Instagram, Facebook, TikTok and WhatsApp

has been restricted in Turkey on multiple networks.

Netblocks said the access blockage came as the main

opposition Republican People's Party (CHP) called for rallies

after police set up barricades in areas around the party's

headquarters in Istanbul.

According to data from Turkey's Freedom of Expression

Association, which monitors local censorship on the internet,

the access problems began at 2045 GMT on Sunday, with bandwidth

being throttled for the platforms.

Turkey's Access Providers Union, responsible for

implementing internet blocking decisions, did not immediately

respond to a request for comment about the access restrictions.
