Qatar. In September, the emir reiterated his sovereignty over the town and the Kubaisi and naim tribe. Grant replied by arguing that there was no special mention of the Kubaisi and naim or Zubarah in any British treaties signed with Bahrain. A government official agreed with his views and concurred "that it was desirable that the Chief of Bahrain should, as far as practicable abstain from interfering in complications on the mainland." The Al Khalifa witnessed another opportunity to renew their claim on the town in 1874 after a Bahraini opposition leader named Nasir bin Mubarak moved to Qatar. They believed that Mubarak, with the assistance of Jassim bin Mohammed Al Thani, would attack the Kunaisi,s living in Zubarah as a prelude to an invasion of Bahrain. As a result, a body of Bahraini reinforcements were sent to Zubarah, much to the disapproval of the British who suggested that the emir was involving himself in complications. Edward Ross made it apparent that a government council decision advised the sheikh that he should not interfere in the affairs of Qatar. However, the Al Khalifa remained in frequent contact with the Naim, drafting 100 members of the tribe in their army and offering them financial assistance. In September 1878, a number of Zubarans were involved in an act of piracy on a passing boat which resulted in the death of four people. Political resident Edward Ross demanded that the Ottoman authorities punish the townspeople for the crime, and extended an offer of British naval assistance. He held a meeting with wāli Abdullah Pasha in Basra to finalize the deal. Shortly after the British-Ottoman meeting, Jassim bin Mohammed Al Thani and Nasir bin Mubarak attacked Zubarah with a force of 2,000 armed men. By 22 October, Jassim bin Mohammed's army, having sacked the town, now surrounded Murair Fort, which was fortified by 500 members of the Kubaisi tribe. The Kubaisi eventually surrendered to Jassim bin Mohammed's forces on unfavorable terms and most of the Zubarah's residents were relocated to Doha. The incident aggravated the ruler of Bahrain due to his treaty with the Kubaisi tribe. There were reports in 1888 that Jassim intended to restore the city so that it could serve as a base for his son-in-law to attack Bahrain, but he renounced his plans after being warned by the British.
