Woman injures three people in third Poland school knife attack in a week
Confirmed
In Short: The incident follows two previous attacks earlier in the week: a 19-year-old student attacked nine people at a vocational school in the Mazovian province, and another attack in Ostroleka, north-eastern Poland, injured seven people, as reported by the BBC (United Kingdom) and Arabnews (Saudi Arabia).

A 21-year-old woman attacked three people at a Warsaw school on Saturday, using a dangerous object, according to Jakub Filipiak, a spokesman for Warsaw police, as reported by Al Jazeera (Qatar).
Al Jazeera (Qatar) and Arabnews (Saudi Arabia) reported that the attack occurred at TEB Edukacja, a post-secondary education institution, while students were submitting papers at the school office. The injured included a 17-year-old girl and two other women aged 17 and 24, who were also submitting enrolment documents, as per Poland's state news agency, cited by the BBC (United Kingdom).
Al Jazeera (Qatar) and Arabnews (Saudi Arabia) noted that police had detained 76 people across Poland in connection with these incidents and had checked nearly 50,000 schools nationwide to prevent further violence. The BBC (United Kingdom) reported that 59 schools preemptively suspended classes on Friday, primarily in the Mazovian district, where Warsaw is located.
Al Jazeera (Qatar) reported that the suspect had entered Poland from Germany and was traveling east towards the Korczowa border crossing with Ukraine, according to prosecutors.
The Kyivindependent (Ukraine) reported that Poland's Foreign Minister Radoslaw Sikorski had visited Kyiv's main train station on September 10, and that Poland remains concerned about economic competition from Ukraine, particularly in agriculture and trucking.
The BBC (United Kingdom) reported that the Ukrainian embassy in Poland condemned the latest attack, and that a priest had been killed and four others injured in a separate knife attack in south-east Poland.
The attacks have prompted Poland to issue safety updates and prepare for potential threats, with the interior ministry publishing information on how to respond to air attacks and expanding on a safety handbook sent to all 17 million households earlier this year.
Despite the differing details provided by various outlets, all agree that a series of violent incidents, including the latest attack at a Warsaw school, have occurred in Poland, leading to heightened security measures and public concern.
What this adds
The BACKGROUND notes that seven people were injured in a school attack in Poland, while another incident at a convent left one priest dead and four others wounded.
