March 12 (Reuters) - Medical ‌device maker ​Stryker ​said on Thursday a cyberattack that hit its computer systems ‌a day earlier is causing widespread disruption ⁠to its business, including its ability to ‌process orders, make products ‌and ship them to customers.

An Iranian-linked hacking group called Handala claimed responsibility for ​the attack, saying it was in retaliation to a strike on a ⁠girls' school in Minab, southern Iran.

The school was hit on ​the first day of U.S.-Israeli attacks on Iran, killing an estimated 150 ​students, according to Iran's ‌ambassador to the U.N. in Geneva, Ali Bahreini. Reuters has ⁠not independently verified the figure.

Stryker first disclosed the issue on March 11, saying it ⁠had experienced a global disruption to its Microsoft environment.

The ​incident has not affected any patient-related services and its connected medical products, the company said, even ‌though the full scale and financial impact are not yet ‌known.

The company, which has 56,000 employees and ⁠operations in 61 ‌countries, said its ​investigation is ongoing.
