DUBAI — The United Arab Emirates executed a UAE woman convicted of terrorism early on Monday, after the militant-inspired killing of an American kindergarten teacher in December 2014, the state news agency WAM reported.

Ala’a Badr Abdullah al-Hashemi, 31, was sentenced to death on June 29 for stabbing Romanian-born Ibolya Ryan, a mother of 11-year-old twins, in the bathroom of an Abu Dhabi shopping mall and attempting to bomb an American-Egyptian doctor.

Hashemi was also convicted of setting up a social media account to spread militant ideology with the intention of undermining the government and of giving money to militant organizations for attacks, WAM reported.

The report did not disclose how Hashemi was executed.

Police said last year Hashemi had become radicalized over the internet and had not been targeting an American in particular, but was looking for a foreigner to kill at random.

Attacks on Westerners are rare in the UAE, a wealthy oil exporter and tourism hub, but concern has been rising after a spate of terrorist attacks in other Gulf countries including Saudi Arabia and Kuwait.

Hashemi claimed at her trial that a mental illness was behind her actions and described herself as being possessed by evil spirits. During her trial she occasionally burst into tears or bouts of laughter, the newspaper said.

A medical report commissioned by the court found she was sane.
