Top updates on Pakistan-Iran fighting:

• The United Nations and the United States have appealed for restraint after Iran and Pakistan traded deadly airstrikes on militant targets on each other's territory. UN chief Antonio Guterres called on the two governments to "exercise maximum restraint".
• The military action between the heavily armed neighbours has further triggered tensions already heightened by the Israel-Hamas war.
• Pakistan's retaliation comes days before the February 8 general elections. Shuja Nawaz, distinguished fellow and founding director of the South Asia Center of the Atlantic Council, said a weak caretaker government in Pakistan cobbled together to hold the elections may not be best equipped to deal with these complicated issues, allowing the military to take the centre stage yet again.
• Pakistan's strikes came after Iran carried out raids on what it described as "terrorist" targets in Pakistan on Tuesday, killing at least two children.
