From Al-Jazeera…

Turkish police have used tear gas to break up May Day demonstrations in Istanbul, arresting up to 700 people, including half a dozen union leaders.
Disk, the country’s labour confederation, said at least one person was badly hurt in the violence as police used water cannons against protesters armed with Molotov cocktails on Tuesday afternoon.
The march was called to commemorate the 30th anniversary of a deadly rally at the city’s central Taksim Square, when unidentified armed men opened fire on a crowd of peaceful demonstrators, sparking panic that left 34 dead.
Transport was paralysed as the authorities blocked roads.
Ferries were cancelled and metro stations closed to cope with two crowds on either side of the Bosphorus.
