Twitter offered no explanation for the sudden suspension on Saturday.

Social media platform Twitter has suspended the account of Al-Jazeera Arabic amid a wider diplomatic dispute between Qatar and Arab nations.

Twitter offered no explanation for the sudden suspension on Saturday, though it comes after Arab nations have blocked websites and broadcasts by Doha-based Al-Jazeera.

Another Al-Jazeera Arabic account described the move as part of an “organized campaign” targeting it. Al-Jazeera has said it has come under cyberattack as well amid the diplomatic crisis.

San Francisco-based Twitter did not immediately respond to a request for comment. Among its top investors is Saudi billionaire Prince Alwaleed bin Talal, a member of the kingdom’s royal family.

Saudi Arabia has led other Arab nations in cutting diplomatic ties to Qatar on June 5 over allegations the nation supports extremists. Qatar long has denied that.
