BELEK, Turkey (Reuters) - World leaders promised to tighten border controls, step up intelligence sharing and crack down on terrorist financing at a summit in Turkey on Monday, but there was little sign of a dramatic shift in strategy against Islamic State in Syria.
The G20 summit in Turkey's coastal province of Antalya has been dominated by Friday's suicide bombings and shootings in Paris, which killed 129 people and underlined the threat posed by the radical jihadist group far beyond its strongholds in Syria and Iraq.
