(Reuters) - Online food-ordering company Grubhub on Friday said it was ending a partnership with Russian tech giant Yandex NV for driverless robots that deliver food to college students.

The announcement came as Russian firms are being shunned globally over the invasion of Ukraine. Grubhub is a unit of Just Eat Takeaway.com NV, Europe's largest meal delivery company.
