US-Iran talks are in doubt as ceasefire nears an end

US officials have announced that Vice President JD Vance's trip to Pakistan for peace talks with Iran is on hold, as a two-week truce was set to expire and both countries warned that, without a deal, they were prepared to resume fighting. Iran said on Tuesday it had still yet to decide whether to attend the talks. FRANCE 24's Reza Sayah reports from Tehran.
