As Israeli attacks on Iran, and Tehran’s retaliatory strikes, enter their sixth day, the deepening conflict is sparking fears in Islamabad, say analysts, rooted in its complex ties with Tehran and the even greater unease at the prospect of the Israeli military’s aerial influence extending close to the Pakistani border.

Pakistan has closed all its border crossings with neighboring Iran for an indefinite period, provincial officials said on Monday, as Israel and Iran trade intense strikes and threaten further attacks.

Pakistan has recalled some of its diplomats, non-essential staff, and their families from Tehran due to the escalating Israel-Iran conflict and the changing regional situation.
