Update | Taiwan protesters march on President Ma Ying-jeou's office to demand halt to trade pact
Rejecting president's concessions, students and other citizens rally outside his Taipei office to voice opposition to trade deal with Beijing
Watch: Taiwan stages mass anti-China trade pact rally
Tens of thousands of Taiwanese gathered outside embattled President Ma Ying-jeou's office yesterday to increase pressure on him to retract a trade pact with Beijing that they say would hurt the island's economy.
The massive protest went ahead despite Ma offering concessions the night before to further scrutinise agreements with the mainland.
Wearing black shirts and yellow headbands, the protesters - shouting "Ma Ying-jeou, step down", "Safeguard our democracy" and "Withdraw the trade service pact" - rallied in front of Ma's office. Organisers said 500,000 came, while police put the figure at no more than 120,000.
They flooded most areas surrounding the Presidential Office Building along Chongqing South Road, with streets packed as far back as the Taipei Station 1.5 kilometres away, and to the legislature where some 200 students have been occupying the parliament chamber since March 18.
