In Bangladesh, the opposition Awami League has called for more anti-government strikes later this week, as the country emerged from a three-day nationwide work stoppage.
Violence between police and strikers over the three days injured more than 200 people.
Awami chief Sheikh Hasina called the most recent strike after a grenade attack on her party's rally left five people dead, including a former finance minister.
The planned strikes would overlap with a regional (SAARC) summit of South Asian leaders in Dhaka on Sunday and Monday.
Prime Minister Khaleda Zia condemned the grenade blast and vowed to bring the attackers to justice. The government has formed a commission of inquiry and sought help from the FBI and Interpol.
