Israel says tank 'accidentally' strikes Egyptian post

JERUSALEM -- An Israeli tank "accidentally" fired and hit an Egyptian military post on Sunday, the Israel Defense Forces (IDF) said in a statement.

The Egyptian post is located in the area of Kerem Shalom, near the Israel-Egypt border and southern Gaza Strip, amid heavy fighting between Israel and Hamas, a Palestinian Islamist group, in Gaza.

There were no immediate reports of casualties.

"The incident is being investigated and the details are under review," the Israeli military said. The military also expressed "sorrow regarding the incident."
